Game you regret buying

L4D2 - It was not my type. I understood it later.
Limbo - I like it but it is short.

L4D2 / MW2 / Bioshock 2 / ME2
Apparently I have problems with sequels

I REGRET NOTHIIIIIING> Well maybe CoD MW2 but i still spent a lot of hours in it so it was worth it i guess...

Bully - poor graphic and control on pc

Gothic - poor ui and control (it will be a good game if I've bought it ten years earlier)

Left 4 Dead - I just hate this game for no reason

Left 4 Dead 2 - same as L4D

Sniper: Ghost Warrior - some bugs in single player (pc) made the campaign impossible to finish

Wasteland Angels: AI bug on pc made this game very boring and disappointing

Counter Strike Source cuz right after my friend gifted me CSS(he miss clicked and bought 2 gifts instead of one)

Definitely that failure of a game known as 'Brink' by Splash Damage.

Plain Sight. Bought it full price and regret it.

Flatout 3

L4D2 and Portal 2 pre-order.

Spectromancer I think it was 15$ back when I bought it too
Also Hoard, Magicka (almost at full price)

Actually there's so many games I got on steam sales I regret getting. I can't count...! Damn you steaaammm

Dragon Age: Origins.

Uhhhh, let's see...
CoD4, E.Y.E., Garry's Mod, Madballs, QuantZ, and some games in bundles were pretty disappointing, but this is it, more or less.

Dragon Age: Origins - I regret paying full price when it was new, instead of waiting for the version that had all the dlc and expansion bundled in.

Bioshock 2 - I bought the ce on release and regretted it within 5 minutes of installing.

Audiosurf

Freedom Force

Freedom Force vs. the 3rd Reich

Magicka

Worms Reloaded

MW3...WHY I BOUUUUGHHHT THAT GAMEEE!!!

Flight Control HD - was on sale, but damn it's boring
Post Apocalyptic Mayhem - bought fourpack, i don't like it... maybe someone from my giveaways enjoy it moe than I

I regret nothing. Even if I don't play them I like to collect my games :D

Dungeons and Dragons: Daggerdale

Red Orchestra: Ostfront 41-45 (dead)
Fable III (still playing through it, though, my opinion may change a bit)
GTA Complete Pack (I won't play them all)
Saints Row: The Third (I regret buying at the price I bought. I have barely played it)
GTA Chinatown Wars (not fun)
Ninja Gaiden Sigma (DMC 3 is way better)

Nothing.

I preordered Alien VS Predator at 50€, i thought it would be a very good game, etc.
But i was really disappointed... Online suxx, not enough players.

Hunted: The Demon’s Forge... worst game ever

I can't say that there is a game that I regretted buying, especially if I bought it at full price.
Yet, there are some games that I'd remove from my library if I could. They are mostly games included in bundles or game packs, either indie games that didn't work out as planned, or very old games that have no purpose at all.

CoD MW3

all of them.
