Civilization V, especially considering it might often stay open all weekend on the second monitor. Also saw Eve Online mentioned; that took untold amounts of my life, but I’ve been clean for a long time o/. Arma 3 with it’s various mods also has well over a thousand, what with it’s endless modular gameplay and annoying ass realism (hiking sim). But right now at this very moment I’ve got X4 going on a few hundie. I’ve heard it called Eve Offline; I dunno if it’s exactly that, but it can be incredibly frustrating and clunky, but also crack cocaine. I think I’ve just barely figured out how to play it.

Lanaaaa!
