We actually waited until the game was officially released and live until our reviewer finished writing his text (he was at home working on it for the first part of yesterday). In cases where there's a a significant enough online component we'll typically wait until we can test it in real-world situations before giving the game a final grade.IGN
"The final game code that we received used the same online servers as the beta test, which we were in for a few weeks before LittleBigPlanet was released. We were given full access to the online component in the game for our review, so we were able to do everything that the retail game allows, including four-player sessions with folks in later levels of the game."Gamespot
LittleBigPlanet was reviewed using a retail copy of the game that was able to connect to a server set up by SCEE ahead of the full release. This, on top of time spent checking out user-created content in the beta, afforded us ample opportunity to test all of the game's online features. We weren't able to see how the retail servers will perform under the weight of hundreds of thousands of users, of course, but that's true of any review for an online game that comes out prior to or even right around the day of release. If the online portion of the game doesn't perform properly at launch then that's something we'll report on.
