Description: The best thing: is fully modable. There're tons of stuff in the web available for free: Cars: many types of openwheels (Including the amazing 2005 F1 & 1979 F1 mods, GTs, rally, street cars, karts, off road, etc. Tracks: oval, historic, rally, hillclimb, real, karting, etc. Of course, is not perfect, but is the best racing sim out there IMO. GTR2 and GTL use the same game engine, but it's netcode is not as good as rFactor is. And aren't so modable. You must give this gem a try if you like racing sims!! ;)
