Also iirc, all the complaints about Tribes Vengence were based on the Multiplayer aspect and the Single Player game was well recieved by most critics.
Alas, Tribes has always been about multiplayer so that's the only thing that really mattered. Single-player was decent but failed to capture the essence of Tribes. They shouldn't have even wasted any time on a single-player campaign but I'm sure Vivendi forced them to.
