I don't consider them to be as different as you - and others - do. They are platformers and pretty much play the same. Some are 2D, some are 3D.
Don't get me wrong. The Galaxy games are great. The rest I don't like.
Yet, they are all very similar (i.e. Mario Platformers)
And I say it again: Being on 4 different consoles doesn't mean they are not annualized games, which Serebii was referring to.
Maybe I'm alone with that opinion, but I don't think this is a rant at Nintendo, at all (sometimes my - and others' - wording may make it come across like that, but it's not my - our - intention; apologies).
It's perfectly reasonable criticism, and we also give alternatives to Nintendo's current approach to gaming (as seen in many threads over the past few months).
As @Daft says, other companies get their fair share of criticism, but they also have several 'attack points' (negative: new games of a series each year - positive: also new new games; Child of Light, etc).
EA sucks. Still, I buy Fifa every freaking year
