I haven’t played a Metroidvania in a while and I’m looking for suggestions of some good ones to try. Some I would recommend:
Ender’s: Lilies (Magnolias is good too, but play Lilies first. The setting and theme hits better.)
Ori and the Blind Forest / Will of the Wisps (Will of the Wisps did bring a tear to my eye)
Monster Sanctuary (a creature capture metroidvania)
Any system is good, interested to hear of other good ones that are out there.
I don’t know if it’s “favorite”, but an old classic was Aquaria. It had a surprising amount of content, even to the point of several secret bosses, and an absolutely excellent soundtrack. Sadly, the main guy behind it is dead now. Ori was also fantastic.
