PC here as well. Sure, you can drive over all but the nearly vertical mountains... but hit the slightest bump and the Mako is like a superball. Mako was fun at first, but planetside gets tedious fast: loading screen - bounce - bounce - hit anomoly 1/2/3 and do same minigame for all - bounce - short, unsatisfying vehicle firefight - loading screen. ME2 was much better - here's a planet, grab the resources, if there's a special mission, then you get a loading screen.
