Root........for those non Australians.......that means having a naughty, not barracking for your favourite team lol.
It's a typo guys. As you can see on your keyboard, the R and F are really near, and an ISI guy, you know, the one with big fingers, created the trademark like this....Pfiuuuuu, it's so obvious!
If you want to know the story... Well... Remember when X Factor was a buzz word? "Go for the x factor!" ISI were being talked to by a publisher, and told to find the X Factor in what they produced, and folks at ISI thought it was funny (which it is, I imagine everyone saying X Factor in a business context to look like David Brent), so they named the title rFactor, r standing for Race.
