i purchased, the warz (now known as infestation survivor stories when it came out, and was denied a refund on it by team :( it is way too p2p

Years ago, I bought the original Unreal Tournament for the PS2 and that port was terrible! It had very slow and glitchy gameplay, and using a controller just didn't work at all! If you want that true Unreal experience, get the PC version. Or try UT2004! :P

I own many games that I don't care for, but I either got them ridiculously cheap or in a giveaway that I don't regret them at all.

I'm pretty sure I purchased Afterfall Insanity, though. and I don't like that game. It's icky.

Well, I just looked it up, and I only paid $3.40 for Afterfall, so I guess I don't regret it so much. Ha!

Syberia 1+2 collection. Not a bad game (the first one), it just took me so long to get to it in my backlog, and when I did, I only played like 7 hours before getting bored. I still have yet to play the second game, but I bought it on a 75% off sale for like $3, so it wasn't that much of a loss.

Guild Wars 2. Again, I'm not going to call this a bad game...but I only got like 20 hours out of my $30 purchase, and considering that I have spent far less on games, and gotten far more time out them (heck, I think I got that same amount of time out of the World of Warcraft demo), this was a much bigger loss.

A few, I guess, but most fresh on my mind is Castle of Illusion (the remake). I didn't pay that much but it still felt like a waste, since (a) the game forces a mix of English and German on me, since it sets the game language to the language of my OS by force, with no other way to change it apart from changing my OS settings, and it only offers English voiceovers to begin with, and (b) being so accustomed to the comforts of modern games, I didn't realize it's one of those platformers that make you replay the whole level if you get hit three times, regardless of checkpoints - but what I did realize is that those games aren't for me anymore. And even if they were, I bet that the platforming would be more precise in the original 2D version; not everything is more fun in 2.5 or 3D with moving camera angles.

Dungeon Siege 1. I found it so exceedingly dull that it took me nearly a decade to beat because I kept losing interest.

Fortunately I only paid about $7 for it.

This is an excellent Ultima 5 remake built on the Dungeon Siege 1 engine. It's is not grindy at all, and features a large world full of inhabitants with compelling stories. Dungeon Siege itself is tiresome, I agree. But Lazarus is well worth the $7 you've paid.

edit:
Also, I regret the hell out of Gothic 4: Arcania.

SNIPER: GHOST WARRIOR HOLY SHITTY GAME

Various DRM issues, bad design, no FOV sliders, bugs, etc. Was that at launch?

Star Wars: The Clone Wars on Gamecube... I thought it was a sequel to Rogue Squadron (which is an awesome game) and so bought it before reading any reviews... It was atrocious and awful :/

I'm not sure there are many other games that I've bought and regretted... some Christmas and Birthday presents that maybe weren't great, but usually if I buy something it's because I've put a bit of research into it and have a good idea that I will like it..

The Shivah. These days, with limited free time for gaming (I'm sure most of you will know exactly what I'm talking about), I restrict myself to the three genres I really, really like: Strategy, Adventures and RPGs. Of those three I like the first, but absolutely love the second and third.
So, naturally, I'm a huge fan of Wadjet Eye Games and their creations, especially the Blackwell series. I even liked Resonance, although the ending was a major flop. One day I saw this seemingly neat little game somewhere here on GOG: Shivah. I bought instantly without even reading one review (I'll never do that again...), since how bad can a three-and-a-half-stars game be?

Really, really bad.

Shelter
So boring game, nice art and such but got no enjoyment out of it. I still don't understand the purpose of the game, seemed to lack any sort of story.

Driftmoon
Bought it because it had good reviews. I don't understand why it got good reviews, controls felt clunky too and uninteresting story. Not a big fan of the art style.

Hotline Miami
I'm unable to play this game more than 5 mins or I get a really bad headache. The game was fun otherwise but the constant moving screen makes it impossible to play.

You really shouldn't pay attention to reviews of any article writer, unless there were players, if so fuck 'em even if they think is good and actually is
Zelda Ocarina Of Time, I hate how zelda ALWAYS fucking stops just at the time I am getting hit just when we are 5 seconds away from going out of the fucking castle

Mass Effect 2: Boring, dull and very poor story if you could call it that.

Deus Ex: Well written but gameplay, well there was not much to like at all.

Devil May Cry: Piss poor controls, awful save system.
