Race simulation with a high fun factor, unfortunately, with account registration

The racing game itself gives me a lot of fun, the graphics are great, the sound of the V8 engine, made the environment super, the racetrack etc. Now for the negatives. I'm already logged on Steam since I have purchased GRID 2 and now I am bound not to create an account at Racenet and for that there is a very negative rating, pray as did hers it!
What do you think, if I here 40 - have 50 games and has me at 50 Games Create 50 different accounts, because I lose track of where I come in Devil's kitchen!
