Critics are not always "right". The highest-rated GBA game (at least on Metacritic) is Tony Hawk 2 -- does anyone really think that's the best game the system has to offer? I don't think I'd even put it in a top 100 GBA games list, myself. Another fun fact from Metacritic: Summoner (the original) is "better" than God Hand. Do you agree? How many "real people" share that opinion?
Even when the critics are "right", a score doesn't tell the whole story. Resident Evil 2 has a high score on PSX. But who wants to play it on PSX today? It has since been released on N64, Dreamcast, PC, and Gamecube, and all of these are substantially better. It's still a good game on Playstation, but practically speaking, it's of little use to note that.
And anyway don't you have your own opinion? I find out if a game is good by playing it, not by mechanically digesting posted scores.
