Cavalary: Shortest one I have no problem considering a proper review, 6197.
Oh, and if you're curious, longest: 19276.
I did a review, pretty sure it was Rebel Galaxy, the ~18k limit in these posts was too short so i had to do 2 posts to do the review...
Depends on how in depth the review needs to be though. At least you don't have to do it in a tweet of 240 something characters...
Heh, though it makes me want to start listening/rewatching Zero Punctuation reviews on games.
Timboli: You can in many cases, just create a thread in the forum for the game and link to that in your review with some kind of preamble. Even if you just indicate your Review on the game page is a summary of a more detailed and extensive review in a thread post in the forum section for that game. If that section doesn't exist, then just use the General forum and explain the case.
Braggadar: That's quite ingenious and an obvious solution I never considered. It also leaves your review open to amendments should you be complaining about a feature / bug of the game which gets fixed later - just edit in a note in your post in the game subforum and your job's done.
I got a thread just like that....
