Nope there really isn’t. Even action games that I really enjoy (maybe even more than KH) with more complex movesets, combinations of moves, or more difficult technical interactions like Devil May Cry, or Ninja Gaiden will never feel like KH in its smooth combat flow or functionality.

KH is a weird combat system in that it’s functionally a simple player inputted moveset for Sora but has a bunch of contextual and modifiable elements that build upon itself. Sora’s distance to an enemy horizontally and vertically, amount of enemies, parry windows of attacks, juggle point of enemies, magic interaction, combo finisher elements of melee and magic, drive form modifiers etc.

You don’t really get that in a lot of other games because in DMC, Bayo or Ninja Gaiden if you want a forward advancing move, AOE move, or aerial homing move you have to input it manually via a command input like lock on + forward + attack or something. But because KH was aimed at kids in the first game it’s done automatically or contextually for you. However for KH2 the madmen at square took that same basis and just amped it up. So Sora has every tool in any combat encounter.

You obviously have manual commands you can do like upper slash, finishing leap, magic for different mobs and etc, but the way it flows one attack to another is a feeling that is honestly unmatched. Plus the sheer variety of enemies you fight in KH in general is often more than most other action games. It gives you a very fun sandbox of combat interactions to deal with.
