Seems nice on the outside: feature-full, all riders, all races. But on the inside it's a completely different story...
I may not know what the goal of a managing game should be, but I do know that what separates video games from other forms of entertainment is the involvement of the player, the use of his skills to succeed. This game, try as it might, lacks this very important notion. The way the game works is as follows: all the racers have definitive statistics for their abilities in various environments (Time-trial, Sprint, Climbing etc.), and these statistics are determined by the performance of their real-world counterparts. For example, Fabian Cancellara was on top form at the end of last season as well as at the beginning of this one. He is, therefore, the strongest racer in time-trials...hence he will win every single time-trial in the game, baring that the player takes control of him and mucks his effort up.
Basically, what I'm saying is that the performance of each rider depends practically only on his capabilities, and not on the way the player manages him during a race. In my opinion, this makes half of the game totally worthless.
Of course, there are other, minor, problems that plague this game: a choice of something like 3 different tracks of electronic music (trust me, you don't want to listen to them after a few stages), a pretty bad user interface which lacks tool-tips in some places, a terrible set of tutorials which teach you very little (in fact, as far as the time-trial tutorial is concerned, I'm wondering if it was even designed for this version of the game; it was telling me things that simply were impossible; there is definitely a bug) and a VERY laggy mouse cursor (although that could just be my crap PC).
All in all, the game is packed full of content (all the tours, all the classics, loads of stuff...but nothing that is worth playing. I don't know if I'm going to spend more time on the game. As for now, the easy difficulty seems to be identical to the medium one. Either the guys at Cyanide really want to make it challenging -- and by that I mean sadistically challenging -- or they simply couldn't be bothered to play-test the game fully.
It's a shame; I was hoping for better.
