It's been my experience over the past few years that if you like RPG's. Stay away from pc and consoles in general and buy a DS. They throw out decent to great RPG's on the DS every week it seems I can't even keep up with how many that system has. Don't get me wrong I love my ps3, 360, and wii...
Will it be like Justice League based or more freedom to do what you want?
Will it involve all of the alternite DC universes?
Will Green Latern characters have some kind of limit and not be basically unstoppable?
