Crazy Taxi (aww yeah)
Crazy taxi is quality, but I feel like the challenge mod is SO damn difficult. I got most of the 1 and 2 level stuff, but theres a couple of the 3 that are ridiculous.
Tried out Space Channel 5, its harder then I thought it would be since I you have to time you movements with the beat alone and I pretty much have to have scrolling arrows/color coded buttons to do this shit. Hopefully a little practice is all I need though.
Yeah everyone says 3d sonic games are shit, imo they got shit AFTER the sonic adventure games.this is what i thought too then i bought sonic adventures on psn and guess what? it sucks. it didn't age well at all.
Edit: (Slightly off topic) Has anyone played Sonic Colours? Because it looks pretty damn decent.
Another game that came to mind when I used to have a keyboard + online for the dreamcast; Phantasy Star. I doubt you can still play it though (online).
