I still play now and then. I tend to put it on before or after playing the game I turned the console on for.
I'm pretty decent at it. No where near the top guys though. I have gold on all Hard tracks (including both DLC packs) on Evolution, the odd Platinum here and there, and I have one gold on one Extreme track, but have finished them all. "The forge" and "great fire" from the DLC I found the toughest.
My proudest Trials moment as getting 0 faults on "King of the hill" on Trials HD. I'm pretty sure the first time I got through that track I had over 100 faults, so a massive improvement.
