When I read reviews like "game made foremost for fans of the series" I get instantly discouraged. I just wanted an amazing classic brawler... not something which is dedicated to a niche audience of a niche console of a niche series ... that has too much games to even consider visiting and getting up to date with them.
I hope it still comes on Game Pass (I have not seen them saying anything lately about this) ... but my excitement diminished a lot with the reviews.
That's just developer talk about how they are tried and true when it comes to beat Em ups. I wouldn't worry.
