Almost everything in Tribes 2 is a hover vehicle except the mobile base. But given that the hover-gravs and terra-gravs all have the same 'SHOOT ME" labeling on them they're not much fun to drive around the base.
Hell, driving those things is too much of a pain in the rear to me. But everyone else seems to be able to hop in and bomb everyone else without half a trouble.
Not much to contribute On Topic-wise here, the only two tank games I ever played were for the SNES a long time ago... And even then they sucked. Having to worry about gas, crawling around the map, having to use your machineguns to clear out landmines...
Blah.
Like the military would send ONE Abrams out by itself to attack military strongholds.
