No I ment you're game is using DOOM the F1 2006 one is using certain files from F1 2002. I've checked the language settings but no luck. Oh and you can't fully install it so I suggest you make a folder on your desktop and ut all the files in there.
The pit radio on the 06 one is in spanish, just as warning. No you don't need the base game as its a whole new F1 game just using some of the files from f1 2002. A bit like your game. It's a whole new game just using the doom engin.
