besides an easy AI the game is a masterpiece
AI/Challenge, 6.5/10
But this will allow you to notice the brighter side of the game.
referencing to mario kart, the frame rate in Mario kart Wii was terrible, and for a racing game, you need a top-notch frame rate. i mean the tracks wernt all that big. Zelda Wind Waker had a better frame rate on the overworld, and it must have been 60 times bigger(at least).
so back to the game, the frame rate is simply excellent, and for such a high rate the graphical back up is fairly good.
Graphics,9.5/10
there are plenty of tracks to choose from and tons of modes, and lots of fast cars.The wii mote sideways wasnt good just like in Mario kart ( another refence ) but the wii mote nunchuck combo works great even though the controls arnt what you would expect, with B accelerating and Z braking. One or twice it wont read you pressing the Z button so be sure to watch out.
gameplay,9.5/10, controls, Wii mote alone 2/10, wii mote nunchuck, 10/10.
last but not least replay value, although you wont jump right back to do the challanges again, and the game doesn't have mulityplayer,(thats one point off the total score, seriously NO MULTIPLAYER?) youll come back to again and again if your a racing sim fan.
replay value 9.8/10
if you like racing sims youll like this one, but be ready your gunna be alone.
