I managed to get Einhander from Hollywood video for a bit in the 90s. It was an interesting side scroller.

Hunted down a flac copy of the Soundtrack recently.

The ones that stick out the most in my mind are Einhander from a PS1 demo disc and Sonic Adventure demo for Dreamcast.

Spent a lot of time in both of those, certainly more time than playing the full game for Einhander (since I never got the full game, and I think only ever saw it even once, at a convention decades later).

I still remember competing with my brothers in the Sonic Adventure demo to get fastest times, that was _mostly_ the same as the first level of the first game.
