On DM-Deck16 map!! Firing rockets at the ground to jump up and over to the other side and blasting your mate point blank with the frag gun mid air. God I loved that game and it wasted HOURS of my uni time playing LAN matches across campus.
I won every tournie we set up and played in the 1st year Halls.
When I first got the original CS thoguh I lost my skill. I didn't have the patience for one-shot kills. I rage quit everytime I'd get headshot. I realised I was good at tanking a shot then crazy-dodging and countering. You couldn't do that in CS. So in UT I could take a shot, rocket jump in their direction and shotgun the bastard from behind before they knew what was happening. None of those skills transffered to CS where accuracy and cover was the main aim.
Great collection. I spent endless hours playing Capture the Flag in Unreal Tournament, loading up the rocket launch to unleash when someone popped round the corner. Good times.
Tribes Ascend was amazing; I think it might have been towards the end of the game's popularity, but I loved that they sold a pack to skip the F2P grind progression entirely (kinda like getting a GOTY version a couple years later)
