I bought 2 copies of this game from Amazon before Christmas for myself and my brother in law and I have to say I am extremely impressed by Rfactor. As default the game comes with cars enabling you to race in F1, F3, tarmac rally, formula first and touring cars which sounds alot by comparison to other racing games and then you start to look at the available MOD's on the web which I will come to in a minute. There are a number of unlicensed tracks available in the game including a certain famous Northamptonshire track in the UK which are all accurate down to the bumps in the track surface. The only criticism I would make of the game is that you cannot devise your own championships although there is a program available to download online to do this. The game has a huge online following with MOD's available to download for a wide range of races including Touring Car, Rallycross, Truck racing and also a huge number of accurately modelled tracks meaning that this is practically the only racing game you need. This may not be the prettiest racing game but the lower quality graphics (still looks great to me though) does mean that this will run on lower spec machines contrary to what Mr Evans is incorrectly saying in another review. The min spec for this game is a 1.4Ghz processor, 512Mb RAM and Geforce 4200 or Radeon 9200 128Mb Video card. I highly recommend this game although as previous reviewers have said a good steering wheel is also recommended although keyboard/gamepad control is possible.
