Enhanced huh?
is your analysis. You're right, often games will trend downwards, but that's mainly applied to games that come in with a lot of hype, since the first few reviews may or may not succumb to that hype, and is alot less pronounced for other games. In recent history I know that MGS4 actually trended upward due to a few early lower reviews.
And you're telling me that same sites with different reviewers is enough reason to invalidate comparing two scores from the same sites, but you can use aggregates of completely different sites and that's fine?
Truthfully you have no idea how it will trend, and don't even bring in the idea that a game that was previously released on another platform usually has lower scores even if enhanced simply because the original excitement for the game is long gone.
