Presentation: The UI is okay, it's a racing game, so what do you really expect. The UI elements are bigger than they really need to be, so the screen isn't exactly clean, and feels a little crowded, but this doesn't really impede gameplay. There is no real story to speak of; again, racing game. The menus feel a little weird, like it was designed for a console, not a mouse (though it works fine with a mouse).
The game-play is just bad. All the cars feel squirrelly and hard to control. Some objects in the game look like barriers to avoid, but are knocked away like they were made of styrofoam and will give you points for hitting them. Other, similar looking debris will stop your car dead on impact, and cause you to lose points for even slightly touching them. The physics are just weird, crashing into anything often causes your car to jerk violently to the side (not spinning, sliding laterally), and at no point will any of your tires leave the pavement, no matter how badly you crash. Different paint jobs for your car affect it's performance in the races.
The graphics look fine, but don't impress. Some of the scenery is relatively low-res, but you're not likely to be looking at it in a race. The atmospheric effects are just a variety of skyboxes; there's no weather at all.
The sounds are basically just a variety of revving engines and squealing tires. There is no announcer, or voice acting at all that I noticed.
Additionally, the multi-player is individually hosted. Hosting a server dropped my game to ~10 FPS on the menu screen (and no one joined). I did not see anyone else hosting servers.
In conclusion, playing this made me want to play TrackMania again. If you were thinking of buying a racing game, I'd recommend you pass on this and give TrackMania Nations Forever a look instead; It's free, so you can hardly go wrong there.
