Convinced only halfway line!

Career Mode
At first you start with Wildcard race in Moto3, you have to establish there to get in the next complete season a starting berth.
If you've made it, got a contract, it now starts with its virtual ego in an exciting career. Well, and it is here already comes the first point of criticism: Already after the 3rd race is quickly bored, because at least from that date everything as well as repeated. Be it news from the personal manager or even the newspaper article, it is in principle always the same. Personally I'm a fan of Jorge Lorenzo, in the game he is my taste for something but never too strong, has once flatly all consecutively won 6 of the first 7 races. Is possible, but unlikely. In the newspaper the Top5 of all classes are displayed after a race, even as falling back on very, hardly exist in this game playful surprises such as the one Valentino Rossi maybe from 12th to catch up and will start the Grand Prix even wins. The top 5 are always the same (Lorenzo, Rossi, Pedrosa, Márquez, Crutchlow), from time to time in a different order, but I'm now a full season down in the Moto3 and after each race the 5 were in the top 5. To my taste for something unrealistic and boring at the same time. In short here is missing the special kick, because right here you could have done so much.
Career Mode I rate it with 2 stars out of 5.

Gameplay
Here I must express great praise, the driving behavior of the machines have been very well implemented. In the Moto3 can rush around every bend even at full speed, while you have to watch the MotoGP even when accelerating, which does not slide a motorcycle. The driving behavior can also be adjusted with optional driver aids, so that even beginners can cope with it.
The gameplay I rate 5 out of 5 stars.

Sound
The sound in MotoGP 13 is good, but not perfect. The sound machines in each class, of course, different, but unfortunately a bit too Sporat.
The comments of Edgar Mielke, remain somewhat in the background. Jediglich the beginning and the end of a session is commented by him. However, the sayings are repeated quite quickly and are therefore boring. Comment during the race would have been really great.
The sound I rate 3 out of 5 stars.

Others
You can drive a full championship with his favorite driver, multiplayer (online mode) seems to paint anything else at the moment, I could not test so far unfortunately.
Man with his player profile achieved several "steps" by which you unlock automatically various new things, such as new drivers for all 3 classes, photos of past seasons, new helmets for its virtual ego etc ...
The rest I rate 4 out of 5 stars.

CONCLUSION
For MotoGP fans definitely a very well successful implementation, but a few more wishes unfortunately leaves here and there left.
On the whole, this game is easy to play but it makes for hours of fun and definitely has everything you need for the current MotoGP season.
