Nintendo refused to let them use any of their characters.
Lame. Understandable but lame. Nintendo could fill an entire roster of secret characters and put their stamp on it. It would be epic. Free advertising is always good as well. Plus people go nuts for secret characters anyway. I bet it would sell like crazy.
Yeh.
But personally I find it better the way it is because hey, wouldn't it be kinda lame to see Mario... AGAIN? IN A JUMP'N'RUN?
Go away Caps Lock, the pocks on you.
And I think fans would consider it kinda lame if you have none hidden characters that you don't know and well... all the Nintendo ones once again.
I am more interested in all the indie ones they will pull out off their sleeves. Because they lead me to new interesting indie games.
Didn't know Spelunky before SMB and now I play it almost every day!
And that's just one example...
I remember someone saying something like that on twitter and team meat being all like, "actually no we went to them".
Oh okay..
Well then..

please come out for Wii anyways~~~~~~~~~~~~~~~~
