What innovation could RPGs benefit most from?
For map and miniature focused games, 3 dimensional hologram maps would be really cool. Come to think of it, anything that would make it easier to game long distance. I mean technology like Skype and Google+ Hangouts help, but real-time map interface, with miniature/icon sync, and better signal clarity would really help.
I have friends who moved to Canada, and I miss gaming with them. Or my high school friends, or gamers I've met online.
