Games you wish you never wasted time playing

Mass Effect 3.

Far Cry 1

MW3. hated it and regretted buying it tried to get into it but i never did.

MP: Mafia Wars

SP: None , i don't play crappy games .

LoL and Lineage 2 back in the days. Also a bunch of browser based garbage time-sinkers such as Ogame, Travian and Extremelot (italian-only roleplaying chat). And for single players, The Sims. I was tempted to add Mount and Blade: Warband but it was good fun on a good game, despite it being so FREAKING DAMN slow it made you question why weren't you instead studying quantum physics or something around as abstrusely useless.

Of course... one and boring Dead Island.
I gave this game over 4 hours to stretch its wings - checked multiplayer with friends... singleplayer.

Also Stalker: Clear Sky - just awful sequel.

Day Z

probably world of warcraft

Multiplayer: Need for speed world. The whole game is a scam.

Single player: The thing. Don't get me wrong, it's a great game, but i still have nightmares...
