Do you have any games you bought at full price and still think that they were worth it?

Never bought a game full price but games that IMO would worth their full price are:

• Terarria

• Counter stike (GO)

• The Binding of Isaac

• Rome Total War

• Portal 2

• L4D2

Rocksmith. Had to buy the physical copy because of the guitar cable. It's just awesome :)
Borderlands 2. Preordered the game. Was definitely worth it.

Portal 2. Paid the full $20, and it was worth every penny.

Heroes of Might and Magic 2+3 and Mercenaries (on Xbox) would probably be the only games I bought at full price that I really loved to play. If you've only played Mercenaries 2 you can't imagine how good the first part was...I hated the sequel.

Super Mario Bros. 3
Excite Bike
Doom
FX Fighter
Sam and Max Hit the Road
The Grim Fandango
X-Wing vs. Tie Fighter
Star Wars: Rebellion
Colonization
Half-Life 1
Dark Forces
Total Annihilation
Bioshock 1
Bully
GTA4
The Orange Box
Dead Island
Morrowind
Oblivion
Skyrim
Valkyria Chronicles

And probably a LOT of others that I can't think of right now.

The last game I bought at full price was Halo 2,

I even got the collecters edition tin game box

Incidentally it was also totally worth it considering how many hours i sunk into halo 1 finding every easter egg and then some

still as I got more and more into PC gaming and saw games in get more widely distributed and much cheaper, it was hard to pay full price with such a huge backlog.

I mean a few years ago I thought $10 per game was a steal and bought a copy of everything I could get my hand on the first time I found a used games bin.

Now a days with bundles you can get 4 or 5 games for as little as a few bucks.

skyrim. 150 hours and plan to go back someday and finish it (the main quest at least) now that my pc is upgraded.

The first game I ever bought for a full price was a Final Fantasy VII at the day of release... on that day in my country it cost me 109,95 of today's USD. I bought it for PS3/PSP/PSV as well. And today I bought it on Steam once again. It's my most favorite game even to this day so yes, it was definitely worth it. Something similar I can say only about HOMAM3, which I bought on the day of release and then bought it again 3 times in the past years because I lost the original twice in the hands of lousy friends so now I own one retail and one digital copy just to be safe :)

And from recent years... Magic 2012-2014, Mortal Kombat 9, Portal 2, Far Cry 3, Tekken Tag Tournament 2, Battlefield 3 and Legend of Grimrock are the few that comes to mind... Those were last pre-orders and day 1 purchases I did not regret because I knew they will be awesome. But I got burned many times in the past...

On PC, the only games I remember buying at full price were Skyrim, Saints Row 3, Blood Dragon, and (possibly) Just Cause 2.

For console, I believe I bought pretty much every Gran Turismo game full price on launch day, everything else I bought on sale or used except maybe a couple games that I can't remember.

And from before the PS1 era I didn't buy anything, my moms did.

On PC, the only game on Steam I bought for full price is AvP, from a retail disk. Can't say it was worth it, but at least back then I didn't have enough speed and time to download it over Steam.

Animal Crossing: New Leaf

Torchlight 2.

Several: BL2, BI, Dust, Rogue Legacy, Borderlands, there are others that just aren't popping into my head atm.

Okamiden, Super Hexagon, Counter-Strike, Castle Crashers (twice), Metroid Prime Pinball (Twice), Pokemon Diamond (Twice), Pokemon Mystery Dungeon: Explorers of Time

Counter Strike: Global Offensive (PS3 version): Worth it, i platinumed it on 5 days.
Papo & Yo: I should have waited for a sale, not a good game.
Sound Shapes: Veeery short, and little replay value (in my opinion). Still, i wanted it so bad when it released so i think it was worth it.

At full price I bought only StarCraft II (worth it), Mass Effect 3 CE (don't wanna talk about it), CoD BOI (meh), TF2 (worth it).

Skyrim. Price per hour was like $.20 an hour. Totally worth it to me.

Killing Floor and Plants Vs Zombies.

Back in 1999 I bought Bugs Bunny: Lost in Time for 200FIM, which roughly converts to 34€. I was only eight years old at the time, and it was a HUGE amount of money for me. The next game I paid the full price for was probably Worms World Party the following year, but I have no idea how much it cost back then. I've since lost the CD for Bugs Bunny which I truly regret, and the only other physical copy of a game I own is Nox, but that was from a sale so it doesn't count here.

But after buying Nox I don't think I even bought that many games until joining Steam in 2010 (for a free copy of Portal, encouraged by my friend), and actually starting to use it in late 2010/early 2011 when I discovered Steam sales. I did pay 15€ for VVVVVV outside Steam, though. And now that I think of it, I bought my first HIB because I wanted to have VVVVVV on Steam and couldn't be bothered to email Terry Cavanagh about it (he used to give out Steam codes for those who bought straight from him). I think that was a turning point. I never looked back.

And I'm not merely listing games I've paid the full price for; I truly think all these titles were worth their full prices.

Modern Warfare 2, Black Ops 1, Borderlands 2 and Bioshock Infinite. They're all worth it.

Demon's Souls, Dark Souls, Ni no kuni, Borderlands 2 recently.. naturally all of my SNES/Megadrive/Saturn/Playstation games back then. I usually don't regret buying games, except for few preorders such as Future Soldier and Metal Gear Rising.

SpaceChem. After trying its demo, I couldn't resist buying it right then. $15 well spent. I still think it's the most brilliant puzzle game ever developed. :)

Deus Ex: Human Revolution. Such a fun game!
