That might be a seal of approval for some folks that didn't particularly LIKE the first game. Personally I thought it was ugly and didn't run very well on my then-current rig. There was also enough of a learning curve, especially with skiing, to be offputting, and the "leet" attitude of the community in regard to treating less-than-experts like dogshit didn't help much either. It just wasn't a great experience, so when I hear "not like Tribes at all" my ears perk up.
You can make the exact same argument about any other multiplayer game that has some element of unconventionality that requires practice and skill. Quake 2 had the grappling hook--you either learned to use it, or you sucked. Counter-Strike has its tactical element--play the game like a run-and-gun shooter, and you'll be sitting out most rounds.
There are games like Quake 3, UT/UT2k4, and now Tribes 3 for those who want an experience that starts and ends with "hold the fire button and keep the crosshair over the enemy." If you want a shallow-but-newb-friendly game like that, power to you, there are your games. Some of us wanted a deeper game than the low-ceilinged, hand-holding newb-a-thon that's Tribes 3, though.
Heaven forbid you actually have to learn how to play a game to do well in it. :roll:
