Donkey kong, I hate those games...

Pikmin I suppose, only played the original but it always felt more tedious than strategic.

i think the wii series was just generally no fun, like wii sports. It was ok at a party for like 30mins and then i no longer cared about it ever again to the point where someone could of taken it home and never returned it and i would of never asked for it.

New Super Mario Bros. (which is not the same as neither Super Mario (64,Sunshine,Galaxy) , nor Super Mario 3D (World, Land)) easily, started out great and when downhill, still not bad games in general but bad games for Mario standards

Nothing at all!

The Wii series wasn't really something I played much on my own, but my family and I had a lot of fun with it together, which is something I can't say about most games. Up next would be Mario Party, but I feel I can't hate on that for the same reason as the Wii series.

I'd probably have to say Mother, though I've only actually played Earthbound. The game had charm, but I never felt very attached to it. Special mention would be Ice Climbers, though that's not a franchise obviously.

On the basis of what I've played (admittedly very little) I have to say Zelda.

Which game/s have you played in the series, and for how long?

Easily the Wii series, but I'm also not a big fan of the Kirby series either. Other than Kirby 64 which featured some really cool powerups, Kirby just doesn't do it for me.

And every Yoshi game besides SMW2 Yoshi's Island falls into this category for me as well.

Easily Paper Mario due to it's downward spiral since TTYD and the atrocity that is Sticker Star! Hopefully Paper Mario U will redeem the series, otherwise I'm sticking with Mario & Luigi from now on!
