So each world is going to have it's own arcade machine, containing some "old-school gaming goodness"... What kind of games would you like to see? Would you like to see something along the lines of "Klungo sssavesss teh world"? Or would you rather see a more genuine type of arcade game?
Personally, I hope they take both options, and really the fact that they're even including that is really fun! Really look forward to what they do with that!
