Yeah, sandbox does that. It's a bit of a situation where everyone is gonna either be alone, or some of them will be working towards the same goals. At least from my experience. I'm used to either going solo or getting left behind in roleplays, so I have found myself perfectly fine with being alone and doing my own thing. Not to say I hate character interaction, but most people either have characters I want nothing to do with, or they want nothing to do with me in turn. It's pretty messy, heh.
