I agree, the Mako was a major pain in the neck to drive. Not to mention the terrain they made for the worlds was ALWAYS mountainous and ridiculously hard to navigate.
I have no problems with it at all. Weee, Mako mountain climbing extreme challenge! I've used it on both 360, and PC. No problems. I even climbed an 89.999~ slope once. It took a long ass time, but I did it. Got to somewhere I really shouldn't have.
Navigation was horrid, indeed. The lack of XPs is another thing. I still done it and climbed over near vertical cliff faces, but it was not enjoyable at all. Then again I don't get into car/race/off road games either.
Which brings up another point. You go from an "OMG, I'm in the game" feeling, to a "DIRT" off-road game. That is more immersive breaking than being disturbed in the middle of a fight, by a knock at the door or a phone call.
The planet scanning was tedious, but you have got to have something. What that is exactly?...IDK.
Maybe a marriage of a Shuttle - Taxi - Cannon - Scanner.
