I hope I do not regret getting Super Paper Mario (Wii). I remember thinking it looked kinda barren while watching some playthroughs, though I started to gain interest in how different the story was compared to typical Mario games, and also was encouraged by the defense brought up for it by Chuggaconroy during his own playthrough of the game.
Relatedly, there has been no shortage of wonderful platformers for me to get on Wii U, from Super Mario 3D World, Yoshi's Woolly World, Captain Toad, Rayman Legends, Super Mario Maker, etc, for the Wii U itself, the many compatible Wii platformers such as Kirby's Epic Yarn, Kirby's Return to Dreamland, Kirby's Dream Collection, Wario Land: Shake It!, etc., and virtual console platformers that I missed out from even earlier Nintendo consoles. So I am definitely going to give this less-than-best-loved Paper Mario entry a shot to feed my love for platformers.
