I've always felt as though I'm unable to fully enjoy RPGs. Final Fantasy is one of my favourite series of games, but outside of that it's pretty limited. Undertale was probably the last RPG I played that I liked, mostly because it did something different with the combat system and the puzzle aspects weren't too over the top. I feel the same way about CrossCode, but I would put that game into a different category as it isn't a traditional RPG.
I just don't want to sink a ton of time into a game that is mostly a grind with story elements and payoffs that are few and far between when I could play a different kind of game that is at least continuously stimulating.
I like the timed hits. Makes it a little more than just a standard RPG. Also like the idea of being able to change your party and switch play styles. Whenever I play it now, I make a point to try out a new combination of strategy and characters. This last playthrough, I only used Bowser(once available) and Mallow and every level up when to Att/Def for Mario and Bowser and Magic for Mallow. It also seems to have the perfect balance of difficulty. I want most games I play to be hard enough that I need to think about my actions but not so hard that I keep dying if I don't do everything one specific way.
