Trials Evolution has to be one of the better Arcade games ever released :)
As far as the gameplay goes, the game looks just as good if not better than the first one with the new environments. Loads of tracks and a new liscense system that acts as sort of a little tutorial before advancing to more difficult content. One thing I noticed was the game actually seemed a bit easier than Trials HD. I'm not sure if the physics of the bikes is a little different of if the tracks were easier. Gold medals didnt seem overly difficult to achieve on most tracks for veteran players. I want to say there were about 6 different "zones" of tracks, the first 3 or 4 werent too bad at all, but that changes. Dont take this review as saying the game is too easy. I think the difficulty was set up just right. The challenge on the easier tracks comes with your Platinum medals and trying to better yourself on the leaderboards.
All and all your gonna get a nother great, addicting game. Definately an Arcade title that you dont want to miss.
