I play Super Hexagon, Boson X, and games like that. Any others that are really fun (preferably free)?

Not all free, but:
Super Crate Box
Super Ninja Therapy
Wave Wave
Gravitron
Mini Mix Mayhem
dEXTRIS

Flamekebab

None at all. Ever.


Oh all right, lots.
Super Meat Boy, Team Fortress 2, the Wipeout series, and probably any number of others. It's really a matter of picking a genre and refining from there, to be honest. Fast-paced is a tad too broad.
