Maybe it does deserve that score, but still I'm getting this game. And the thing is there are a lot of wii owners that dont own 360 or PS3, so maybe they'll get this game and enjoy it for what it is, a solid FPS, but nothing special. Hopefully though this is what Wii owners want, and maybe it could be a surprise hit, but yeah it is overrated.
And btw at least gamespot were honest and reviewed it professionally I always thought for one that the IGN review was a bit high, though it's my main review site, but a 75% review score is good enough on gamerankings(seriously metacritics don't know what a C is), and it seems fair. So it's more of whether ur into wii controls or not. I know i like PC controls more than 360-PS3 ones, so Wii FPS is my cup of tea console wise
