Mech Assault 1 & 2, particularly 2. The two most memorable boss fights for me was the mid game one where you fight some giant robot bull thing in a tiny exosuit while Getting Away with Murder by Papa Roach Plays, and the final fight where you fight a half built giant mech again in the exosuit while Right Now by Korn plays.
Also I really liked Halo 2 for the banshee dogfight with Follow by Incubus in the background and the big Mausoleum fight at the end of Gravemind with Blow Me Away by Breaking Benjamin plays; the part where the doors open and the bell starts to toll chefs kiss. Oh and the whole level where you drive a tank up the bridge chasing down a Scarab too.
Also, why has there been no remake of Crimson Skies yet? That game was so much damn fun. I miss the dog fighting and crazy guns.
You just reminded me, I also played the shit out of Unreal Tournament 3 and briefly held a double digit rank in Team Capture the Flag. Loved that game overall and I liked the addition of that hoverboard.
