Thanks, any more?
Tropico 4 + modern times expansion(good city-building game with some humour )
Dawn of Discovery + Venice expansion(also city-building game with more strategy, set in 1404 or smth like that i think)
Minecraft(good but becomes repeating after few years of playing :D)
Mafia 2 (good storyline, set in 40s-50s)
TES: Skyrim
Maybe add your PC specs and your intrests in gaming so we know what to recommend.
You could also watch movies, they are good timekillers :)
I swear, when I first looked at this I was sure it said "Games with no intent" O_O P.S. Old games run on an emulator.
