Seriously!! need a new Ninja Gaiden game (on current gen systems) with 2d gameplay and hd sprites / some variation of cellshading!.. also needs some multiplayer.. 2 players (same console / per console on system link) and up to 2-4 players (online).

Here is a good example of how 2 players would work on the same console

Super Mario X

notice how the dynamic screen combines and splits as the players separate.

now that would just kick ass!! being ryu / his father side by side .. or any other 2 playable characters in the ninja gaiden universe!! game would be the best!!

I wonder when that Super Mario Bros X was made, because I'm sure I've seen a collaboration music for some speed run or something which was impressive.

Because it gives me the funny idea that New Super Mario Bros on Wii wasn't even original as they got the whole Co-oP idea from this game.
