The penultimate game in the Summer of Arcade 2009 promotion on XBLA is released today. Trials HD is a physics-based motorcycle game and comes with over 50 levels to compete in, fifteen skill based mini games and a level editor to create and share your levels with friends. I purchased Trials HD after all of five minutes of playing the demo, it is a really fun game and has just the right balance to make you want to win that Gold medal before playing the next level. I will be writing a review of the game sometime soon, no exact date as I think I will be losing track of it playing this game 
Trials HD costs 1200 
and the demo can be downloaded here.

Easily one of the best arcade games. I really hope we’ll see some sort of level creator scene – there might be months and years of life in it.
It is my favourite XBLA game of the year so far. Easily hours and hours of replay fun to get those gold medals.
