How much would pay for the game that gives full enjoyment for only 2 hours with no replayability?

$5 sound about right. That's still less than one meal.

I think the better the quality, the more I am willing to pay for a game. I am honestly baffled how many people complain about game length and don't even take the actual quality into consideration, when it comes to titles like What Remains of Edit Finch. The game is 20 bucks and lasts 2 or 3 hours. That's pretty short, sure. But you get so much out of it. It is a very unique, highly emotional experience that no other game can offer. It may be over in a few hours, but you won't forget it for years. This game has so much more value to me than most AAA titles. It is easily worth the 20€, and I would even pay more for it. It makes me sad to see so many people ignore the game or even ridicule it, just because they are not able to consider anything but the length to cost ratio. Games like Edith Finch are easily worth their money. They offer a unique experience. They are something truly special. The length is not a weakness, it's a design choice. It's the length needed to tell the story. I mean, would you want to walk around in Tacoma's space station for 50 hours? I wish more people would see that and buy those games on release, so that they are successful and we get to see more of them. But of course most people will ignore every game that offers 2-3 hours for 20€. instead they buy a game like RE7 that offers 7 hours for 60€. ^^

Under $3 is leading, but i think it's really too low, depending on the quality of the game itself. If the game is really well done i can go up to 10-15 euros, i don't really care if a game is long or short if it's enjoyable. People spend full 60 bucks for crappy short games anyway, so they can't really complain if something like Braid is only 3-4 hours long, as long as it's good. For the same reason, i think that extending playtime too much would require the developer extra effort (and money) to develop some new stuff to keep the game fun without resorting to heavy grinding, backtracking and other half assed methods to increase hours. Better short, but good than long, but weak, regardless of price.

Also remember that we used to play at arcade malls with a couple of quarters every five minutes of gameplay, it was expensive as fuck.
Or to put in another perspective, here i spend about 15-20 euros to have an evening out with friends (pricing may vary depending on your town/country). Or 10 euros for a movie at the theater - about one hour and half. So 10-15 euros for a two-hour game is fine for me (and still there are sales and trading if you really want to save some money).

over $20 (If the game gives me full enjoyment, I don't mind)

I have already been paying more for going to the movies with family, which is also around 2 hours of enjoyment without "replayability".

Well ... 2h, then it would be in the range of a movie ticket.

It's tough to say for me, I tend to buy a lot of stuff that looks interesting or like it can scratch an itch I get sometimes, but many I get distracted from/forget about/whatever. I don't think I've made many purchases I really regret, though.

But I don't usually look for too much of what you describe, I'll usually try them if they're in bundles and sound cool, but outside of bundles I usually only buy games I either really want/crave or think would be fun with friends. I don't have any income, though, so that's a big factor, lol.

No more than 2$. More if dependent on game. Be it cool soundtrack, cool story, multiplayer or whatever.

Easy answer: It really depends.

How much are you ready to pay for a movie?
Games that have little replayability value are games for which story makes a huge difference.

Replayability value is also pretty subjective, depending from the game and the players.
Some people would play a game for the story and never play it again. e.g. Someone rushing through Assassins Creed
Some others would play it for the gameplay and love to do it again. e.g. Ocarina of Time fans
Some others can play a game that has a single, simple mechanic over and over again. e.g. Minesweeper, Arcade games, etc.

To give you an idea, I've played Scanner Sombre twice in the same day. I enjoyed both playthroughs. It's a game that has a very special mechanic and a well-established atmosphere and story. But the second run was just as enjoyable as the first.
Would I play it again today? I don't know. Maybe.

We forget stories over time, just like we forget movies.
And we're willing to pay a bunch just to see a movie once, why not the same for video games? The same amount of effort goes into both.
We've all reinstalled an old game just to play it again, even though it seemingly held no replayability value the last time we played it.

Our decision of a product's worth is influenced by how much effort we think went behind it.
Steam sales has changed our view of pricing. Imagine if every once in a while, most things at the grocery store were 75% to 90% off.
How much would that change your view of how much bread is worth? Vegetables? Pasta?
You would know think that it's not worth that much if they're willing to let the prices drop that much.

The thing is, video games is a digital medium. It's not comparable to experiences (watching a movie, bungee jumping) or physical products (DVD, food). Simply because video games can be copied with zero cost. If you have one tomato, you can't magically get another one for free. Same for a DVD disk. But if you have the rights (DRM-free) to a game, then you can have 2, 3, infinite copies of it.
And thus, a video game manufacturer knows that they can make an extra buck by lowering drastically their prices to reach audiences that would not have bought their product in the first place.
If you saw this box of cookies at 90% rebate, wouldn't you buy it even though you usually don't?
Does it mean those cookies are worth less? Not necessarily. If they stayed on the shelves for this long, it's because other people were buying them full price. Same goes for video games.

The Free-To-Play market emerged as a consequence to this devaluation of games. Publishers know that people don't want to pay much for games anymore and expect more and more content for less and less money. And therefore, they leave the entry free, and rather charge for in-game experiences just like a fair would charge you for the individual rides you take.

People think that the publishers and developers are in control, and that they are the reason the game industry is slowly devolving into an all-you-can-buy buffet of minimal-effort products. But the fact is, these people follow the trends to accommodate the needs of their playerbase, which is the only way their can truly succeed. We are at fault here.

I usually look at 50 hours for 25$ as top price so that would be 50 cents per hour. If game offers more and costs less then ist even better. I might be also willing to spend 10% of my overall budget for entertainment so if I had money to burn Id spend 100$ out of 1000$ every month just on steam games. My current budget on steam is around 15$ a month and thats only because I farm and sell items, otherwise Id have 0

I always compare it with the price of a movie ticket... Here in my country a movie ticket goes for like 5 o 6 dollars an thats for 2 hours of fun.
That's the price for a game 3 dollars per hour should be around right.

Once upon a time, I used to gauge the rate for "good entertainment" to seeing a movie. Ten dollars for two hours. Then the price of a movie went way up and I had to reset my gauge, so I used arcade videogames, instead. Twenty dollars for three hours. Then the arcades started putting out "quarter-eater" games while the gaming console market was getting off the ground. I finally switched to using computer game prices as a gauge, and those prices have been pretty consistent.

Generally speaking, I am willing to pay $60 for a solid twenty hours of entertainment. That works out to about 3$/hr. I could therefore be convinced to part with $10 for a two-hour game with no replay value, but it would have to be a very good game. More often than not, however, I focus on buying games I can replay and/or purchase at a considerable discount. (Bundles FTW)

The most I've ever spent for a single game was about $14. The two games in which I've probably spent more time (in each, by itself) than all other games combined--other than that other game, of course--are Civilization 3 Complete and Railroad Tycoon 2. Both now sell for dirt cheap on sale ($1.24 at time of writing). I played literally thousands of hours back when those games were new (long before steam was even a thing, at least for me), and still enjoy them today.

In part because of the enjoyment level that I have gotten and still receive from those two titles and a few other cheap-ish titles with tons of replayability, I have extremely high expectations for what my money ought to purchase, and will not touch (at anywhere near full price) a game as short as you stated Tacoma is @bravoforfree.

And if anyone is interested, the PC games in which I have the most hours & enjoyment are In alphabetical order: Arma 3, Civilization, Civilization 3, Euro Truck Simulator 2, Railroad Tycoon 2

The response here is very skewed to the lower end I am sure. The people I hang out with would say 25+ euro.

If it was such a great experience why focus on how long it was?

Dang. Lots of cheapskates in here.

A Game With Only 2 Hours of gametime would be about 3-5 €(if you can play it more than once in your life) If you can Play it a couple of times in a Year than it would be about 8€
BUT if it has just 2H Playtime and its not good enough to play it someday again its worth max 1€
