honestly there isnt a lot, if your just wanting wiiu grab lost world (mabye boom rise of lyric too but i have yet to beat it so idk if its good) however if we include vwii definetly grab both story book games and colours there my top 5 sonic games and a must play :)

oh both sonic raceing all stars and sonic mania (if you can get the port working) are some great picks aswell :)

they had the sonic advance trilogy for virtual console on the japan eshop but they all have an english language option in-game so its fully playable! theyre on NuSspli near the bottom in the japanese names area!

I'd recommend Sonic Boom: Rise of Lyric, because this game is so much fun!

Sonic & All-stars Racing Transformed and the fanmade Wii U version of Sonic Mania
