i'd say Little King's Story since it borrows elements from both Pikmin and Animal Crossing.
then Tatsunoko Vs. Capcom since is the best fighter on wii next to SSBB (if you own a Classic Controller you could also check Guilty Gear XX Accent Core/plus, one of my favourite fighters ever. JUST. DON'T. PLAY. IT. WITH. THE. WIIMOTE.)
as for horror games you should try Cursed Mountain. it's a game that passed under the radar of many gamers, but since you like old-style re you would probably like this one. It's also build on uncommon theme like buddhism/tibetan religion (their darker sides), has a very original setting and is an original take on a saturated genre. I also Recommend you Silent Hill: Shattered Memories since its one of the best experiences i had this generation. very eerie and with a really good storyline and psichological aspects, it touches mature themes like loss, grief, familiar love, alchoholism and others. Another recomendation is Fragile Dreams. it's like the bastard child of a Jrpg and a Re-style survival horror (inventary and save sistem are taken from old RE), with anime chara design. its a really beautiful and emotional game.
as for platforms, I assume you already own all the marios so i'll go with other games:
de Blob: very fun and original. colorful game with intuitive gameplay and really great soundtrack.
Mushroom Men: quirky design and gameplay that reminds of N64 platforms. this one could be right for you. It's only a little bit short.
