My ideas:
-Make a new Star Fox game, except that it's not an "on-rails shooter", it's free-roam in space! You're not on a fixed path, you can go wherever you want while evading and returning fire to Andross' forces once again. Make it through forces as you try to reach the end of a level without being shot down. Of course, you have Slippy, Falco and Peppy on your side. There still has to be an on-rails section now and again, but stay in space, just good ol' Arwing combat, not by foot.
-For F-Zero, make a new racing game with the cast of F-Zero X. Make the courses more intense, new racers, HD graphics! Not much is needed, but make a new F-Zero game!
-Ice Climbers, honestly, could even receive the New Super Mario Bros. treatment, but do more than just nostalgia pondering. Make it based off the original game, and have 2 player co-op to get to the top of the mountain and reclaim your vegetables. Once you beat the Condor, some clan of yetis (maybe even the Snowmads?) take the vegetables and spread them across the mountain range. Your goal is to make it to the top of each mountain and claim back your resources. A hunger meter could play into this, like Pikmin 3, where at the end of each level you eat a vegetable. Run out of vegetables, and it's game over for you. Of course, there's lives and such (with the Topis and Polar Bears attacking you) but you get the gist.
-MEGA MAN NEEDS A NEW HOME CONSOLE RELEASE.
