I'd LOVE to see 720p Widescreen, 2D re-makes of the Neutopia Games.
As for System, a multi-platform release would be good, for PS3, PS4, XBOX 360, and XBOX Next/720/Duragno/Whatever it winds up being called.
Wii-U would be ok, if I did'na have to use their tablet to play it on a TV.
Although, it would be nice to have an in-game option to switch the screen to the Tablet's screen.
If they made it for PS3, PS4 and Vita, they could, conceivably, let ya switch back and forth from TV and Handheld, as well.
