I love your use of Metacritic Starcraft since you just blindly take the end number and don't care about how the two are different. If you'd looked you'd know that the PS3 version has far fewer reviews (obviously) and those sites that reviewed both are only 3, Eurogamer (same score) IGN (360 better) 1up (PS3 better). So the PS3's lower score won't really mean much until the sites that gave the original game it's higher scores (Play, G4, Cheatcodecentral) weigh in on the new version.
I also love your assertion of "and dropping" as though you can see trends based on this one number you've looked up.
editted edition: I just wanted to add that I'm not interested in this game and don't really give a crap which one ends up better. I simply wanted to call into question Starcraft's extremely basic and flawed analysis.
