I feel somewhat torn about this game. On the one hand it is a competent rally game we had not since Colin McRae Rally 2005 and Richard Burns Rally. On the other hand it has some serious flaws. The game has quite arcady driving physics, and if it is good or not for you, it depends on your personal preferences. This is a proper rally game, so it does not have any Ghymkhana, rallycross or baja nonsense. It contains 4 classes (WRC, WRC 2, WRC 3 and Junior WRC) and 13 rallies with 6 special stages each.
On the other hand the amount of roads is quite limited. Each rally has 6 stages, but there are driven mostly through the same pieces of road, so there are only about 2 unique special stages per rally. The fact that kept us playing old rally games was great amount of special stages and vehicles, there just is not enough of that. The game is capped to 30 frames per second, what is unacceptable for a PC driving game nowadays, but there are some methods to remove this cap. The game still has some bugs, which are not game braking, but still can be annoying for some people.
The bottom line is that if you are into rally games, get it on sale. It has too much flaws to be recommended at full price, but if you can get it cheaper, it is worth playing.
