Structure of Game Reviews

So, almost time to post a first-ever game review.  The thing is, game reviews kind of need to be on-time, and unlike professionals, I just don't have the kind of time I'd like to play a game all the way through in just a few days so as to post a current review.  My solution may be a bit of a cop-out, I suppose, but it's what you're going to get.  For regular games, I'm going to post a "preliminary" review giving you my impressions of the game... Then when I've completed the game, theoretically speaking, I'll give an update and a final rating.
