Although it is indeed a precursor to Vigilante 8, the original game is extremely sim-like. Supposedly it's a lot like a MechWarrior game (though I've never played those) in that you can add and remove armor and chassis reinforcements, slap on a combination of weapons, and modify the car's characteristics via modding, with the idea that (in singleplayer) you gun down baddies for their upgrades, or (in multiplayer) you try to out-fight or out-race your opponents. And the way the game plays, nothing is worthless, but the way you play influences what's useful to you at any given moment. Prime example: Structo Bumper doubles(?) your chassis reinforcements on the front and back of the car, but take up a slot you could be using for something else if you never run into anything or anyone. Also, higher-performance parts (yes, all of them) are much less durable than their stock and lower-performance counterparts, so that you could be running around with an up-armored F1 car but would get slowed down quickly if you took a few hits, specifically in the engine, suspension, and tire areas.
