Seconding the Shadowrun games from Harebrained Schemes. The mechanics in the first one (SR: Returns) are a bit meh, decking kindof sucks, but the story is Pretty Darned Good. Dragonfall follows up with adding a GREAT set of supporting characters, and adds some neat mechanics. Hong Kong is fantastically done, and mixes the best of both.

The story lines are linear, but the stories are rather good. There's a lot of user generated content, and some are OK, but none of them are as good as the original. (I _think_ someone remade the original game's campaign in the Hong Kong engine, but don't recall for sure.)
