I know where you're coming from with that, but I would say it's certainly not like that and not meant to be like that. I forget exactly which indie game it was that made it kind of sound a bit iffy at least with their advertisment about it. Was it Blacklight Retribution or something like that? I can't remember right now.
What this is is more like Minecraft's alpha/beta development, but with more user/fan input including just suggestions. These 2 guys can't do something of this scale completely on their own. Also, there are many many people out there who love doing stuff like this - sims, 3D modeling, vehicle physics, etc - for a hobby. Hell that's how Outerra started out isn't it? You know people actually find game development fun? Games wouldn't exist if nobody did.
