Strikers is actually really good. Imagine Dynasty Warriors, but actually putting the elements of a Persona game first (Weaknesses, Strengths, Persona usage, customization by switching them since Joker has the ability to do that still). Utilizing various Persona 5 mechanics in interesting ways, such as the Baton Pass being used to switch between your party members. Technicals also return, along with being able to utilize Guns (and the ammo resets like in Personal 5 Royal after every battle).
You also get to switch the soundtrack between Strikers, Persona 5, Royal (after beating the game), Persona 4 Golden, Persona 3, Persona 2, Relevations: Persona and Persona. I dunno if this is a Deluxe Edition thing though.
If anything, do not think it's the same... lack of quality that Hyrule Warriors (and HW: Age of Calamity) has as a "Zelda meets Dynasty Warriors" where it's more or less a Zelda skin with Dynasty Warrior gameplay (bar AoC using some BOTW mechanics).
Also Joker can jump and platform. Link cannot do this in HW or HWAoC. Which is weird.
It's also a sequel to P5 OG and not P5 Royal.
The Persona Compendium seems smaller than other Persona games, though it's to be expected since some may not work with the real time action gameplay (and a lot of Personas were carbon copies of each other anyways) but they introduced Persona Points you collect (cannot remember if it's in Royal/OG P5) if you have the maximum amount of Personas you can carry and a mask drops, giving at least some reward to still collecting masks other than "hey you have a full Persona inventory, get rid of one". The PP (heh) can then be used to level up Personas or eventually level up specific stats.
Sooooo is it obvious I really like it now? No spoilers story wise here. It's a good story though.
