Games you regret buying?

The Penumbra Pack. Don't get me wrong, they might be good games, but I suffer from motion sickness, and I think the FoV in those games is very low, so if there isn't any way to change it, I won't be able to play them. :(

All the games that were bundled.

WarZ. But I was in the first batch of screwed over people, and in the small group who actually got steam to refund the money and remove it from my games list :)

"Plain Sight" indie game.

Modenr Warfare 2 - this was the last of cod series I have bought.

HAWX, I bought it on steam sale to play dogfights with friends, because it was very enjoyable when we tried it on lan-party. Two days after I purchased it, game servers were shut down. I'm not buying any UBI game for multiplayer from now on. They did it to us before with two Splinter Cell titles, though we managed to get some fun before it happened, but I got tired of buying new SC title every year. Besides after Pandora Tommorow it wasn't that fun anymore.
But most of all, I regret not having enough free time to play all the games I have. I don't like to hurry when I play.

DLC quest. The good point that I got it only for $1.

most recently was defiance.

Omerta City of Gangsters.

Civilization V pretty boring too much info and the game play is horrible. The trailer is awesome the reviews are positive but the game is so poor.

The stronghold collection when it was on steam, Bastion because I haven't had the urge to play it yet, the whole Tripwire bundle, Napoleon: Total War, should have bought Shogun 2 and of course, last and the least, Ace of Spades.

This was most likely Hitman Absolution for me.

There is no a particular game that I have bought which I regret but just buying bundles and not even playing the games.
But the good thing is that I can give away the games so the people who want them can enjoy the game.

BlazBlue Continuum Shift Extend.
Bought it to play for story, because I heard it's almost a visual novel. Turned out the plot in this game is incomprehensible mess of anime clichés and time travel. I finished story paths of all characters for 100%, there was a lot of drama but none of them achieved anything in the end - villains won and story ended with sequel hook. Totally disappointing.

Brink, worst single-player ever, poor story and boring/repetitive gameplay.

None. Im true gamer.

Counter-strike Global Offensive or Alan wake

Bunch of heroes. done

dark souls.. is very bored

Alien vs. predator

Garry's Mod, Chivalry: MW, and Borderlands 2

So far, nothing.

"Naval War: Arctic Circle" and "Commander: Conquest of the Americas"
