I played Tremulous for years until it started to fall apart at the seams. I have to say that I'm looking the direction that you took with the game. I haven't really played it enough to get the game play changes well enough but the graphic is good, the animations the maps. From what I've seen its quite good.
The one thing which is hard to get used to though is the 90 minute games. So far I've had two games lasting 90 minutes and while they were on a server that was so far away that lag amongst made it unplayable when the turrets were firing it was fun.
The other day I played a game with three others, two of them old time players as well, and they were so excited to see the game and the work that's been done.
