Wow. You guys must be amazing riders, because a lot of the races were very difficult for me. Well, golding licenses was easy (except for the graduation tests), and the road challenges and road bike races were a piece of cake, but most of the RM races themselves at least felt hard, like I had to really push it every time. Partly this was due to the spread, and also because it seemed like I could never 'get away' from the AI like I could in Gran Turismo. Every split I would nervously watch the time difference, hoping I could finish the race before my 2 second lead dwindled away. One crash and it was all over. The TZ125 and Suzuka Enduro Bike races were especially difficult.
Not to mention how difficult I found it to not wipe out... although, I play with the normal controller mode and no penalties, and I think it tends to make me go head over handlebars because of the lean ability (My hands are too big for the controller, so my thumb tends to push up when I turn).
Granted, i was able to win most of the races, but it never felt 'easy.'
