28. Not THAT old, but still.
How can you say they did nothing with the series when they tried to make their own original ideas? Now, I myself don't own a single DKC game. I only have DK64. And I'm fine with that. I rarely pick up the Play Control or the "Revival" ames. I don't like them, at all. I like originality. Unfortunately, they think capitalizing off of old crap is a good idea. I don't. It can go worse. I mean, the DS Zelda games are meh at best due to some fairly bad idea.(mainly the way the controls work, outside of items) The rest kept going with innovation and it worked beautifully. That's how it's done.
I've played all the Yoshi games(except the DS remake). They're great games, and a lot of fun. I own all the Wario Land(save VB) games, Wario World, and that's it. I love them platformers. I do try to get most Mario main series(and Kart and Party), but I avoid the remakes/revivals because they're really nothing of importance to me. I like Bowser Jr. now, but he doesn't add anything to them. The items are cool, I admit, but both versions did not immerse me into it. Super Mario 3D Land, which I have yet to try, but do own, looks like I can finally get a new 3D version worth playing to me.
