There were several different Playstation / Playstation 1 games from -WAY- back then, that I can't fully remember what they are, but enjoyed quite a bit. Pretty sure they were on Demo Discs.
Edit: I need to learn how to do a strike through on this website.
There was another game that had you using a Dragon fighting another Dragon. They had a Sword and Shield each. After the fight, you could choose another creature from what looked like a factory esque Pod Room. But then the demo ended.
There's another game that I physically can not remember, but could probably recognise if shown. Lots of games like that, actually. Mainly on the Playstation / 1 line.
Edit: If we can add Arcade Games, I wanna add one. You used a Sword, and had to wave it / slash / (heh) guard through an enormous round sensor inorder to input anything into the game. It was a Japanese stylish game. You were slashing up demons, including a Giant Monster whose foot was either a boss or a miniboss, as well as a Ninja like Cat Demon. The Big Bad of the game was the sword that rivaled yours, forged from the depths of hell, Soul Stealer, and you had the sword Light Bringer. And you're trying to save your girlfriend. Or some female. Weird that I can remember so much about it and yet not know what it's called...

Edit: Searching through the thread has revealed the first game to be Tomba. His hair looked Purple in game, so I thought it was Blue, but the Box Art has him with Pink Hair. XD
