For the record, Akira Psycho Ball is quite good.
And I was actually able to play THQ's Genesis Akira game back at a CES show ages ago (this, of course, pre-dated E3). Somewhere at my parent's house, I still have a sales flyer for the game with info and screens on it. I'll have to try to dig it up next time I'm there and get that puppy scanned.
If I remember correctly, it was announced for Genesis, SNES, Sega CD, Game Boy, and Game Gear, although I believe that the Genesis version was the only one on display on the show floor.
The main gimmick of the game was that each stage played differently. Lemme see how many I can recall...
- A motorcycle racing stage that was a lot like Super Hang-On. As you would imagine, you were Kaneda racing against the Clowns.
- A FPS stage where you were Tetsuo wandering though the lab where he was being experimented on. Instead of a gun at the bottom of the screen, you just saw Tetsuo's hand, and when you fired at guards, he shot out a blast of psychic energy. This stage was about as impressive looking as a FPS could look on the Genesis.
- A side scrolling stage where you were Kaneda and Kei piloting that hover vehicle through the sewers. These stages weren't strictly side scrolling, though, as they were quite large and maze-like. You could fly quite a ways up and down as well as left and right. You used the gun on the vehicle to shoot down the guards' crafts.
- An isometric stage (think Viewpoint) where you were Tetsuo walking across the bridge (the one he would eventually destroy). Pressing the attack button caused him to swing his arm out in front of him, sending a wave of psychic energy out in front on him. The main enemy that I recall in this stage were rows of soldiers armed with the laser cannons from the movie. I remember being really impressed with the look of the Tetsuo sprite on this stage (complete with his tattered red cape).
- The last stage that I remember was a 2D beat-em-up (or was it a one-on-one fight?). Either way, you were a surprisingly large mutated Tetsuo attacking, well, whoever it was attacking you (Kaneda? Soldiers? I don't remember).
Seeing as how I was a big fan of the movie at the time, I talked to one of the head PR people at length about the game. She even gave me an animation cel from the movie (of the giant teddy bear and rabbit that attacked Tetsuo), which they were probably giving out to the press.
Even though I was just a scrub working at Babbage's at the time (yes, I was one of those retail kids who snuck into the show), she gave me her business card and I kept in contact with her for a while getting updates on the game. Until, of course, she gave me the sad news one day that they had cancelled it.
Man, I really gotta find that sales sheet now.
