Oh, regarding, Pokeniu, Ephraim kind of has to be Luvdisc, if you're going to use any DLer.
Literally didn't see Mightyena on the list.
Why can't he be both?!?!?
Regarding Wii U games for Shale...
Captain Toad, from my understanding, is worth the price based on reviews and what (non-trolls) have to say about it. It's apparently like 70 stages long, and apparently it'll have Amiibo Support, though who knows what that is. Based on how long the stages were in SM3W, I'd say 10 hours sounds about right, though apparently there's a lot of optional collectibles you're unlikely to get on a first time playthrough, so you can go back and probably get your money's worth that way. It is priced at $40 for a reason, after all.
Wonderful 101 is a fun and quirky game, also made by Platinum Games. It's what happens when you combine Okami, Bayonetta, and Pikmin into one game. If that sounds like a mixture for a train wreck, you are absolutely right, the game is exactly that, and it makes full use of it's train-wreck status to be entertaining!
Sonic Lost World is decent; it's not as good as the "Rush to Win" games (particularly Colors and Generations) but it's solid in it's own right, especially after the patch fixed some of it's issues. Worth at least checking out.
Regarding DKCTF vs. DKCR?
DKCTF is indeed a step up from it's predecessor, but said predecessor has the advantage of a portable variant, so may be worth grabbing for that reason alone. They're pretty much the same on core gameplay, just DKCTF has multiple partner characters, a new "KONG POW" ability that you will never use because you often forget it exists, and more importantly, tighter and more unique stage design. DKCR's a fine game of course, and worth playing, especially since it's portable and DKCTF is not. I wouldn't say DKCTF makes DKCR meaningless, but the two are similar enough that if you like one, there's a good chance you'll like the other. It's a lot like classic Mega Man in that regard.
