Bundle Stars Bundle #2: "Indie Jam" - 10 Titles on Steam for Cheap!

Well, when you are about to pay for a game, whether it is 0,5€ or 60€, quality matters. So even if they offered 50 games, all of them of a bad quality, doesn't mean the price is good.

You're missing the point. If you take 10 games randomly out of the massive number that exist, there's a high chance that they won't be worth €5 combined. You can't say that "...less than 5€ for ten games is not a bad price." without taking into account the quality. There's no such thing as a base price for a game. As with any digital product, the price is only dependent on how much the customer is willing to pay and how low a price the seller can accept for a copy of the product.

Ah, I get it. Although, you neglect to consider that most people will only be interested in some of the games, not all of them, and the uninteresting ones will probably be valued at close to $0.00. So the full price of the bundle will be split only among the interesting ones. Also, it's completely reasonable to value a game you're interested in at $0.50 or less, if your interest is "I have a massive backlog, so I probably won't play this anytime soon, if at all, but I still want to give it a shot eventually." This level of interest seems to have become common with the rise of the bundles. People are now buying games that they normally wouldn't even have considered, only because they're available at a sufficiently low price. Low enough that, even if the game is disappointing, it won't be a major loss. And, generally, if even 1 game from a bundle turns out to be a previously overlooked gem in a person's eyes, the whole purchase was worth it. I believe this is the main reason why bundles sell so much.

With the above in mind, I don't see it as unreasonable to want to pay $1 for this bundle. There's nothing exceptional in it, regardless of your genre preferences, and anyone with a sufficiently large backlog will have only a minor interest in these games.
