Other than being 3rd person action games, neither have much in common.
Hi-Fi is a 3rd person Action Rhythm Brawler in the style of a PS2 game (think
DMC combined with
Jet Set Radio and
Guitaroo Man) with modern sensibilities.
Forspoken focuses on mainly projectile combat with magic and melee mixed in-between, but is more of an Action-RPG. At the same time, Square just wanted to
FFXV again, but with only slightly better combat and magic system.
Amen to that, brother! This type of shit dates all the way back to the SNES/Genesis days on the playground, lunch time, or after school. I got sick of it by the mid sixth generation era, and anyone trying that shit I told them to screw off. Either enjoy your game(s) or don't, but leave me out of your dumb elitist shit.
