Well first off. I just know they got an all new Guilty gear game up their sleeves somewhere coming in the works for the new systems. I really want an all new GG game.
But The other fighting games id love them to do or if they ever got license are:
Jojos Bizzare Adventure
BlazBlue Vs GGX (2 on 2 with strikers)
Wind Ninja Chronicles (ninja Scroll)
Battle Fantasia 2
Basara X2
Bleach
Dungeons & dragons (side scroll beat em up)
&
Maybe help develop a new Guardian Heroes game. action packed and optional Multiplayer Co op online....
How about you forum? what would you like Aksys to develop?
