This game was excellent. Real cars that you can upgrade with real parts, visible performance changes depending on how you pimp your ride, massive maps to race on and explore, a slew of challenging missions, dozens of race circuits to compete in, wonderful physics that work for off-road racing, and a bit of humor. This game might just be what got me into cars. Despite being released in late 2001, I feel like this game is still a real gem.
4x4 Evolution is now public domain and can be downloaded anywhere, but I’d really encourage you to play 4x4 Evo. 2, since it has a ton of new features that build off of the first game.
