Uhh any strategy game ever? I mean strategy games are usually great time sinks. But other than that, modded skyrim? Bioshock series Mass Effect series Assassins creed series GTA V even Battlefield Bad Company Series Uncharted series (Playstation exlcusives)
Oh Sniper Elite V2 and 3 XCOM: The Bureau Declassified oh and a few others I kinda left out strategy games I am pretty sure how you feel about em.
