Even if we assume that everyone who plays AM2R ignores every indie Metroidvania on the market right now, we already know that those games can be successful. Guacamelee and Ori have both sold over 500k on PC alone. Whether Nintendo wants to ignore this fact or not is up to them.
EXACTLY.
And after all this time, it's pretty clear that they simply aren't interested, especially when the best titles in the genre still hit Nintendo platforms.
Which is why people thinking that they would just be cool with this is all the more crazy to me. This project doesn't push people towards existing metroid products. It doesn't push them towards other products on the eshop. It doesn't raise awareness towards the metroid projects in the pipeline. It actively distracts the public eye from what Nintendo is ACTUALLY doing with Metroid while providing 0 avenues for new revenue. OF COURSE THEY WOULD KILL THIS!
