So, I finally sat down with Trials.
After playing up to unlocking Hard...
I can see why it would be fun. But the physics are really bad. Majority of the time, you mess up, its because the physics did something wonky. You hit your head - crash. You land on a ramp - crash. You hit gas, suddenly you wind up on your back - crash. I'm all for trial and error, but a lot of this feels not user error, but instead game error. The fun:frustrating ratio is not in your favor. Why bother making a motorbike game, when most of the time you'll find yourself making slow progress up ramps in fear of the physics throwing you for a loop? You're also given not much control over your character while in the air, at least it doesnt feel that way.
But if you dont mind crashing, this is a fun game. The track designs are pretty nice.
