The playing time is not the longest, but adequate (is becoming their money). There are a large number of routes that have been beautifully designed and unlike Motortstorm: Pacific Rift, are very well arranged. The number of engine and Karosseriteile is enormous and are further enhanced by won races in single player.
One can build his ATV as one pleases. Moreover, this is necessary because different engine parts, bring higher jumps or leave the ATV accelerate faster. There are three types of races (races, Sprint, Freestyle), a private ATV is necessary for each individual mode to be the best (by several garages that you gradually unlock, this is possible).
Just the multiplayer is something entäsuchend, because I've never been able to go through players lack multiplayer matches. The highest I got together, three other players were ....... (up to 16 are possible). I do not know if I set something wrong, because even in the quick search, was my highest result, three. Moreover splitscreen is not possible in this game.
Conclusion: On the whole, a damn good racing game, with unfortunately weak multiplayer mode or players lack.
