What games do you regret purchasing?

If I have to name only one it would be DayZ

CoD MW3. If only I could delete it from my acc... D:

Don't Starve. I realised it wasn't my type of game. As well as the Lego games.

StarForge

Anything old for bringing back memories. In the end I managed to shatter some of those memories by trying to play those old games now. It is a bad idea to buy games that I used to play 10-15 years ago. In my memory they were great and I prefer them to stay that way. If I play them now, I will subconsiously judge them with modern standards. Only 1 game couldn't break the "awesomeness" by playing it now, Septerra Core. Old GTA, Old Tomb Raider, Simcity 2000 (great waste of my money) e.t.c. cannot withstand the time that has passed. It is like watching the original transformers now. When I was a kid, they were perfect. I know now that if I try and watch it again, I will lose that memory of them being great.

Edit: The above does not apply to classics like pac man e.t.c. Those are legends, not games.

pretty much everything

Resi 6

Dark Souls 2 Season Pass

The Raven: Legacy of a Master Thief
The title sounds really cool and I thought I'd enjoy the story, but nope. It was a bit TOO slow paced, and I just couldn't bring myself to care about the deadfully uninteresting characters >_<

Borederlands 2.

None really..I only buy games that are on sale and bundle games.The games are so cheap that even if the game sucks big time it's worth.And now that I have probably more than 100 games that I REALLY want to play like XCOM declassified,darkness 2,arkham origins,outlast,amnesia a machine for pigs and many many more indies as well..I guess I will never have to buy a full price game or a pre-purchase ever.

Skyrim. I've barely played the darn thing.

-Eternity's Child: It looked like it could be a fun platformer, and it had a unique art style. But nothing feels well made, the controls feel floaty, the animations are horrible, collision detection feels off, enemies can take too much damage, platforms feel placed haphazardly and the game is not even finished (not that that really matters, I would not play the second half anyway).
-Dead Island: It's incredibly repetitive.
-Sherlock Holmes: Mystery of the Mummy: I like the other games in the series, but this one is terrible. Boring puzzles, pixel hunting and poor voice acting.
-Assassin's Creed 1: I'm glad I actually dared to play the later games in the series, because those are actually quite alright, but the first AC is just so repetitive.

Arma ii combined operations

Doorways, a fucking robbery, 2 chapters on 4 (2 hours long, developer changed their mind and made chapter 3 a separate game that ive to pay again to play

Preordering God Mode.

And if that wasn't enough I bought R.I.P.D. without realizing it was a skinned God Mode. And it also ended in a bundle

Icewind dale - I don't have a time to play this game much

Company of Heroes 2. Because I can't play it, full of graphic bugs :(

Oh and Starbound and DayZ Standalone, although I loved the mod.

Nothing really, if I had to choose something it would be Modern Warfare 3, but I got it dirtcheap, so I don't care about that.

Aliens Colonial Marines: Collector's Edition

For me it's Viscera Cleanup Detail: Santa's Rampage. The game runs pretty bad for me and the FOV and camera sway make me feel sick within 10 seconds of play with no options to disable or change them. At least it wasn't that expensive...

Payday 2 but it was during sales...and Assetto Corsa my first and last early access game...
