Gamers and reviewers are on different wavelengths for sure.
It's really weird that reviewers consistently give recycled slop like Medal of Honor solid 7 or 8/10, but they cry a river over every "simplistic" and "casual" game that comes out. Most of the mainstream, popular games with minimal challenge or creativity I personally consider casual (most of EA's products, generic FPS games) because they're so lowest-common-denominator.
