Ok, this generation alone Nintendo has brought back Advance Wars, WarioWare, Metroid and Famicom Detective Club.
Despite what I've said earlier, I can't add Donkey Kong to this round because I can't be certain whether or not Nintendo is burying that franchise.
I'm still picking F-Zero here, because it has been ages since we got a new one, but I'd really like new installments of the other Nintendo franchises on this poll.
Which one are you hoping comes back next? :)
