Everyone talks about which Dreamcast games that they want to see on 360/PS3. Why not Propeller Arena?
http://en.wikipedia.org/wiki/Propeller_ArenaThe game went gold but was never released because one stage had sky scrapers you could fly into and 9/11 just happened. The game was done and got leaked in 2004. I played it on my DC and it's entirely complete. However ten years have passed so that 'Anything that vaguely looks like 9/11 needs to be erased' mentality is gone, the game is done, it's made by AM-2 and it's unreleased.
You'd think that Sega could even capitalize on the 'A Dreamcast game that you've never played!' angle. It's multiplayer element is even ideal to be utalized by XBL and PSN.
Every time I see someone make a list of DC games that they'd love to see re-released, no one ever says Propeller Arena and I say 'Why not?'
