Just finished Vampire Masquerade Bloodlines that i got for $5 during the Impulse Halloween sale. No in game clock, but i estimate that it took me about 37 hours. i'm glad i only payed $5, for that price its pretty good. The women models are excellent, swaying hips and tits, sexy outfits. Probably the most risque game i've played.
Alien Swarm is free on Steam, so i might play that next or maybe Painkiller Black that i got during the Halloween sale on Steam.
