The main problem is they tried to sell this game based on star power, and it doesn't have any. They should've tried to sell the game on its unique take on the brawler genre, and how it's a fun, accessible game that works well in FFA and 2 v 2.
It has literally all of the biggest stars Sony owns.
Which doesn't do too much imo. Those characters aren't really THAT known.
