Developer: Nintendo EPD
For a while there, I thought Nintendo was going to keep pumping out New Super Mario Bros games every other year, but it's been 10 years since New Super Luigi U came out in 2013, The Year of Luigi. It's been nothing but 3D and Mario Maker games since then. So how does Nintendo top the creativity we saw in Odyssey and Mario Maker? Not by making another NSMB.
Super Mario Bros Wonder is 2D Mario after taking off the training weights. It's not held back by the rules and conventions of previous games. It feels like Mario with the freedom to do anything as creative as Odyssey, and well, you don't even get the tools to do most of this stuff in Mario Maker.
I also have to mention how good the HD rumble in this game is. It actually plays music as you run over music note blocks. Yes, the rumble plays music. You can feel your character's feet as they land jumps, go in and out of pipes, slide down walls, swim, and all sorts of stuff. I haven't felt HD rumble this cool since Mario Odyssey. You should definitely turn it on for this game.
