the additional cars are a really nice addition to the game but tokyo challenge is so poorly made and balanced that as a whole i considered giving this a lower rating than the original. maybe it works a little better if you play it in conjunction with the main game but being a completely separate menu option with a few minutes of loading time to get between them kneecaps that immediately. try playing it after you finish the story (or even just get to the point where you unlock the A class), and you spend your time alternating between piss-easy races in exotics and brutal championships with cars 2-3 classes above your requirement.

i'll write a more positive review for the base game eventually, but the only thing saving this from being below it (as a whole, i know you can just not play tokyo challenge) is the novelty of riding in mc3r's beautiful carlist in a reused map 3x better than the maps made for the real game
