Ok so I am not going to give you a MAHOOSIVE lo-down on this game, I'm sure you will find plenty of proffesional reviews online... I will give you my opinions on what is good and not so good on the game...
Good solid racing enjoyment.
Accuratley scaled tracks.
Accurate differences between bike performances which, realisticly DONT overpower other bikes so there is no "Ultimate Unbeatable Motocycle".
The inclusion of 125cc and 250cc bikes and races.
Lots of things to do - Lengthy Career with various customisation options such as amount of laps per race, weather etc, quick race mode, online mode, challege mode, time attack mode....
The bike physics at some points are absolutley dreadful, honestly, I am appauled to be fair however this doesnt really affect the gameplay directly.
The simulation mode with championship A.I setting is brutally difficult, in my opinion but some would say this makes the game challenging.
The graphics seem bland with the exception of the bike and rider.
REASONS NOT TO BUY THE GAME:
If you are a graphics whore, you wont want to buy this game JUST for graphics.
If you want some challenging achivements as these are pretty easy, with the exception of the few Simulation and Champion achievments.
I havent actually reviewed it, I just said some flaws and good things, but in my opinion, its a great game and if you love the MotoGP, this is YOUR game.... simple, 5 stars
