So this summer I'm hoping to get some of my non-gaming friends to sit down with me and help me play through some games. I'm looking for any good suggestions for games which allow for someone to be involved with a game even if they don't have a controller in their hands. This could be through a lot of story choices (like RPG like things or ME dialogue choices) and/or a game with a very cinematic feel to watching. Effectively I'm looking for a game that would have me be "driving" but can be played like a team... an endurance run like game.
So yeah, anyone know any good ideas? I only have the 360 or PC, so I'm limited to those.
