It's hard to review a game like this...
The product's quality is astonishing.
Perfect game, perfect graphics, perfect online, perfect editor.
The only issue is that, this package, is mostly similar to the "Trackmania Nations Forever" one, which is free, or to the "Stadium" mode of "Trackmania United Forever".
So if you're a new fan of the trackmania universe buy this game right away, but if you already play on the Stadium (standard) or Nations packages, you might avoid buying this one (Though i still recommend getting it, if you have the money).
I hafve to say that this package features some brand new cool blocks to the editor and Nadeo's tracks are something amazing!
For the first time playing the single player really is an enjoable experience aswell.
I recommend the game.
