Way too much stuff, but loving it all:
I started a new, more serious playthrough of Captain Toad: Treasure Tracker on the Wii U. Goddamn, what an amazingly charming and fun game to play. I usually can't wait until my next play session. My only (very minor) beef is that they don't tell you the condition to 100% a level until you've finished the level, and me being a completionist means I sometimes have to play the levels twice. But that's not too bad considering how incredibly fun the game is.
I've gone back to my Saturn and played quite a bit of Street Fighter II': Hyper Fighting from the Capcom Generation 5 compilation. This compilation is amazing. The games are probably 99% arcade perfect. Animations, colors, hit boxes -- they're all there. And all with practically no loading. (There is a very minimal amount of loading only before a match, but you never actually see a "now loading" screen). The art galleries are also pretty nice.
I've also fired up Vampire Savior, and again, Capcom was pulling off some serious technical wizardry late in the Saturn's lifespan. That godlike 4MB cart gives you a Vampire game that is also 99% arcade perfect, also with practically no loading. Bulleta is so much damn fun to play.
One game that I'm torn on is Super Street Fighter II X as it is in the Street Fighter Collection for the Saturn. I love SSF2X, depending on the day it might be my favorite fighting game ever. This is a good looking port, and as far as I can tell all of the animations and most hit boxes are there. But man... That loading sucks. It's not terrible compared to some of the other games of the time (hello KoF 97), but also not great. But even worse, is that there is noticeable slowdown in some stages. Zangief's stage and Dee Jay's stage are noticeably worse than the others for some reason. Also, sometimes my special moves don't come out reliably, not sure the reason why. In other versions of the game (Dreamcast, etc) I can pull off special moves reliably, but not here for some reason. Oh well, it's still SSF2X, and I still enjoy it despite these flaws.
