Ruffian Games, the developer behind Crackdown 2, was working on a remake of Streets of Rage. We're not sure what happened to the game, but some footage of the unfinished product leaked online.

You may recall Marvel Nemesis: Rise of the Imperfects for the last generation of consoles, or you may not because it wasn't a huge success. In any case, it appears that there was a pseudo-sequel in the works for the current generation of consoles. There is a little bit of video from the game, which you can check out here, but it doesn't show any gameplay. It only shows the menus from the game.

Indiana Jones and the Staff of Kings (PS3, Xbox 360) – The Staff of Kings did release on Wii, PlayStation 2, DS, and PSP, but the reason that this game earns a spot on this list is because the Xbox 360 and PlayStation 3 versions never saw the light of day. The game received a lot of coverage at assorted press events because its demo highlighted the impressive Euphoria physics engine that made 3D characters move and react without the need for animation. The system would later be used in Grand Theft Auto IV and Star Wars: The Force Unleashed among many others. Apparently the cancellation came about after numerous delays, and Lucas Arts shifted focus towards getting The Force Unleashed out the door.

Mega Man Universe (PS3, Xbox 360) – Mega Man Universe was announced into existence with an awesome stop-animated short film, that revealed very little about what exactly the game was. After a few gameplay trailers, some disappointing showings to the public, and the departure of Keiji Inafune - the man who created Mega Man - from Capcom, the project was officially canceled.

Pirates of the Caribbean: Armada of the Damned (PS3, Xbox 360) – This entry into the Pirates of the Caribbean franchise was looking very promising to everyone who saw it. The game had fun combat and took its conversation cues from Mass Effect. Disney Interactive lost a lot of money when its first few releases weren’t the runaway successes they were supposed to be, and Disney decided that they weren’t going to be able to continue dropping money into Armada of the Damned. It’s too bad, because it was sounding pretty good.
