Well i play a lot of simracing (simulated racing) or did (as i don't have that much time anymore). Anyway i've played a lot of sim racing, and i really like it. I have a racing wheel + pedals for computer, and it's really fun to drive around, especially when you play it online.
When i drive, i surely concentrate a lot, and nothing can disturb me, when i'm driving, everything you need to have in mind!!! where's the other cars on the track, is there anyone behind me, shall i break hard or shall i be careful? which gear am I an, where on the track am i? When shall i change gear, shall i turn hard or soft... and a lot more.
Some time ago i read, that it isn't games like GTA or CoD which makes people violent. It should be racing game, like for instance sim racing games, but i think i can find a lot of people, who can tell i'm not a violent person at all :D
to show you what sim racing is, here's a video clip. Notice it's not me who's driving in this video, but the video is captured in GTR2, which i play too. so have fun and enjoy.
