"Leak Express: New Metroid 2D for Switch could be "Metroid Dread"
It would be the sequel to Fusion.
This game...
I hope they expand on the exploration a lot. Dread is great, but it's missing something. They did improve on Samus Returns with Dread, so I'm sure they'll continue to improve with the next one.
Who knows, maybe thier third Metroid game could dethrone Nintendos third Metroid game?
The idea of a Metroid 6 is very intriguing to me, since it would apparently mean a whole new story arc, with the Metroids and the X both extinct. Wonder what that would look like.
I'd prefer it if they weren't, honestly. There have been enough Metroid games as of recent; especially counting Prime 4, if that ever comes out. These games are extremely replayable.
Hope they take another break - not necessarily for as long - and preferably without Mercury Steam at the helm next time. Could surely do without the misguided focus on 'cinematic action' - just let me play the game, man.
Is it reproachable to be satisfied? On that note, I don't think wanting game series to continue forever, ad nauseam, is desirable. There's an incalculable value to closure.
Phantasy Star, for instance, ended on the fourth game, released in 1993, and was never really revived - Online is a separate series - which is something I have major respect for in having been done. The development team and fans got their closure, and naturally moved on - and the series was much better for it. It's eternalized, with a beginning and an end.
Much vitriol has been given to entertainment industries for rehashing, but the truth of the matter is that they're only supplying for a demand. For as a long as people don't think 'enough', they will puppet corpses around. Really loving something is knowing when to let it go - to live forever in your memory.
That all said, I still think Metroid has places to go - and I don't want that potential to be blown away by the breakneck production of new titles. The more different from each other that they are, while still being Metroid, the better - and the passage of time pays service to that.
