It got a reasonably average score of 6.2 and on Metacritic it's achieved an average of 72.
My opinion of it all is that Tom Goodchild and his team at Monumental have done brilliantly in using what limited resources and options for game design to create a decent game.
Lets face it. After listening to Tom's speech during Industry Week it was apparent that they were extremely restricted in terms of how much they can put into the game creativity-wise because of the strict guidelines from Capcom and the MotoGP big-wigs. Yet Tom seems to have worked some magic here and created a solid game with decent replay incentives too.
It's interesting to hear GT's view on the audio after listening to Tom about the struggles they had with it as it is apparent in the game. I'll be honest and say the audio is pretty poor. The bikes sound monotone and there is no audio for the AI bikes (why?). One thing I noticed is when viewing behind the bike during a race all sound (apart from the background music) cut off entirely. Pretty weird and something they could have fixed.
Apart from that I'm pleased for Tom and his team. He seemed extremely nervous about the incoming reviews and I'm glad to see them kinda pay off.
It's obvious they'll be making the next instalment and now they have the new engine and foundations laid out I'm sure Monumental and Tom can crack down and improve on an already solid game.
Good on them!
