Going by metacritic ratings is terrible. If you do that, Super Mario Galaxy is supposedly the second best game ever and New Super Mario Bros. Wii doesn't even rank in the top ten for its own system. However, the vast majority of people are going to get a hell of a lot more enjoyment out of NSMBW. In five years people will remember SMG as a solid title to have sitting on the shelf but they'll still want to PLAY NSMBW. This caries over to others, too, like GTA4 which is supposedly the best game ever, yet most GTA fans I know don't think it's even the best in its series.
Really, review numbers are purely subjective, and are often influenced by cash flows rather than genuine quality. There have been reviewers that have even quit and made a big deal about it publicly when their editors force them to change reviews for games with large advertising budgets behind them like Kane and Lynch. These numbers speak almost nothing to actual quality, and there are many games from this gen not even on that list that blow all of those games away.
You do not have the right to never be offended.
