[@CaptainSully] I'm guessing larger living areas lead to being able to store more stuff, so that's in line with what I was thinking. Plus garages for vehicles.

PvP seems like a gamble, as it should be. You have the chance to kill and loot some powerful items from other players but could just as easily lose your best equipment in the process.

There should probably be some kind of loss attributed to PvE deaths. A loss of money at least, rather than a loss of items.

[@Vocab] looks like your right; there are levels for your avatar that caps at 99. It increases your attributes and lets you unlock new objects and weapons, so I guess some gear is level capped.
