In my opinion, a Year of Toad would actually be great. What it'd contain would be the hard part, though, since they couldn't really just shove Toad into everything...
sadly.
On topic, though, I really think that CT: TT should include Toadette (and Toadsworth) as playable characters. That'd be fun. Not really needed, but still cool to have. I also think that it'd be SO cool to make your own puzzles. Close to 0% chance of happening, but it'd be fun and cool, and boost the longevity of the game.
Speaking of which, I wonder what will boost the longevity of the game? Will there be a few mini-games along the way of you completing puzzles, like how in SM3DW, the CT levels were like the mini-games? Would there be jigsaw puzzles with Toadette helping you out? Mazes where you play as Toadette? Probably not because then they'd have to make a new game out of that too, haha. It'd still be cool, though.
And speaking of mini-games in CT, I wonder if CT: TT will be a New Super Luigi Bros. U situation, though, where it's DLC for it's respective game and you have the option to just get it physical. I wonder this, because recently there's been talks of it being not $60, but $40. I'm personally hoping for it to be it's own game, and not DLC, but either way works. If it is like a NSLBU situation, though, I doubt that there would be Toadette themed mini-games
I also went digging through my Club Nintendo surveys to fill out the Mario ones to notify Ninty about Toad. This is going to sound funny, and here it is; when I was finished completing a few of them, I thought
"Hmm. What if they actually responded by putting Toad in more games. Then it'd be a cool way to make them put cool characters I like in more games! What if I try it with Toadette? Toadsworth? Lana? Oh, I know!
Daisy!"
in all honesty tho Daisy's kinda cool. I just wish, like Toad, that she appeared in more games. ofc Toad has higher priority tho in my surveys, lol.
