Super Mario Wonder is the best 2D Mario since Super Mario World. There is so much attention to detail and the polish on every aspect from the gameplay to the way enemies act and react.
Super Mario RPG is the ultimate remake. It kept absolutely everything about the original while adding a few minor gameplay enhancements. Best of all, the graphics look like the original CG readers from the 90s but with perfect modern sharpness.
Deathbulge Battle of the Bands was an unexpected favourite. It's a light-hearted turned based RPG with Earthbound and Undertale vibes, an amazing soundtrack and interesting and humorous characters.
