You should have said you don't get platformer at all.
I can't said that i don't get what people like about any games.
I'm surprise of what i read here.
I like platformers, not a lot, but some of them. and I really enjoyed SMB 1-3 on my NES (long, long time ago).
I also played some new "iterations" on Wii and (3)DS, but never finished them, because I got bored of them pretty fast. I don't get why they are selling so much, when it's basically the same as every other mario jump n' run game before. And as far as I can remember, you don't play a Mario game for the story either (usually the princes get's kidnapped). So... it's basically the same as CoD, just in another genre with another target group. at least thats my opinion/impression
