Ok, I apologize about the title, first off.
Damn you NG and your 35 character limit!
Anyway, the real title for the game is called PlayStation All-Stars Battle Royale. This, obviously, will be a Sony exclusive that will be released on the PS3 and the PS Vita. The game is currently in development, being made by a fresh, new company called SuperBot Entertainment. Don't worry, though; they have employees who have some experience in the fighting game field (i.e. Mortal Kombat, Street Fighter, etc).
Confirmed characters thus-far are:
-Parappa the Rapper
Rumored Characters include:
-Jak and Daxter
A unique system in this game probably has to be the stages. Instead of a stage from just one game, they decided to mix aspects from at least two different games.
Stages confirmed so far are:
-Hades (God of War/Patapon)
-Metropolis (Ratchet and Clank/God of War)
-Sandover Village (Jak & Daxter/Hotshots Golf)
So, discuss and rave on whether it's too much like SSB or whether it's just fine the way it is. Either way, have fun discussing it all.
