Typically, most sites that are used in aggregate scores of metacritic and gamerankings are (on average) within 5% to 10% of the aggregate score ... At the same time, most of the sites on metacritic and gamerankings have games where they are (up to) 30% or 40% off of the aggregate review scores.
What this means is that it is likely that Sonic and the Black Knight will (likely) see many more reviews in the 60% to 80% range based on the number of reviews that have already been released in that range, but that doesn't necessarily mean there is anything wrong with IGN's review; well, beyond the obvious problems of what is wrong with game reviews in general. From the sound of it, SatBK seems to be a break from what IGN enjoyed from more typical Sonic games and reviewed the game harshly because of it ...
