The graphics are a decent down-port that still looks nice enough, the interface is slick, there is offline and 6 player online multiplayer and leaderboards, a ton of tracks and skins to unlock, the full track editor, and seemingly everything that makes TM great.
Then you find out that players cannot actually download custom tracks outside official DLC and friend-only (using the friend code system with a game specific code, not even taking advantage of developments that allow the use of the system's own code and friend list seen in newer games) sharing.
The Wii is not a PC, users can't just hop on a website and download custom content, so by not building a backend to support uploading and downloading custom tracks from any user, ranked by popularity, ratings, themes, type, etc, like EA's Boom Blox Bash Party for Wii did over a year ago (this uses a similar track creation so the transferred files are really tiny, just including the positioning of the various track pieces you use), Firebrand have effectively ripped off half the game's heart and appeal.
I was hyped for this even after learning the Bay theme was absent, but without the ability to easily get and compete worldwide on custom tracks, I'm not. This is a shame as almost everything else seems spot-on, you can even upload ghosts for high scores, though there's also no Country selection/ranks, and some other things.
I just can't believe Nadeo allowed a port of TM without this critical component.
My 2 cents, the reason I won't be buying it at launch price, if at all, and the reason I'll be telling friends to stick with Nations or get United for cheap.
Don't blame the Wii audience if this doesn't sell so well, the game is still good but it has lost half its point of existence for many (and barely anyone knows it's out)...
