Mass Effect, easily.
I'd love to live in a futuristic space apartment overlooking the Citadel hanging out with my wacky Krogan neighbour and awkwardly dating a friendly Quarian girl from across the hall. And of course my job would be something involving lasers and making out with Asari girls. Oh and one of my co-workers is a Turian named Gerald.
Plus if I'm lucky I'd get to meet Shepard, Ashley, Wrex, Garrus, Tali and Liara at some point while crossing in space.
Man that'd be awesome.
