8 player Mario Strikers seems like it could be wild, though I don't have that many friends that would be willing to invest time and money into it

Pretty cool though.
Nintendo teased us hard by revealing Mother 1 and 2. I honestly thought they were finally gonna drop the bomb and announce a Mother 3 localization...oh well, maybe next time.
The Dread Mode difficulty for Metroid Dread seems kinda lazy. I would much rather have enemies have faster attack patterns or even new ones. Combine it with the future boss rush mode and perhaps a randomizer mode and I'd pay for that as DLC.
Triangle Strategy still is on my horizon, really hoping that choice mechanic is implemented well as it seems like a different concept than the typical good or evil choices.
Xenoblade Chronicles 3 is cool as well. Seems like they were indeed hinting at something with the portals in the Xeno 1 Epilogue and some sort of cross worlds thing is happening between the worlds of 1 and 2.
