I remember hearing about Palworld a couple years back, and at the time I was completely sure it was just a joke. Turns out it wasn't, and I can't help but think it one of the most hilarious things to ever exist in the industry. Any description of this game sounds made up for the ridiculousness of its compiled elements; I'm sure no one expected the developers to have any serious intentions with the project, especially given the accusations that followed its release.
That being said, my interest is the same as always, and so I forgo any investment into such considerations if favor of recognizing the very real effort put into its music. Tatsuya Yano's style seems to be ironically emulative of other styles from comparable game series, specifically Monster Hunter, with elements of JRPG. Some pieces seem to indicate a jazz influence, but it doesn't seem overly prevalent yet; perhaps as the game continues to develop, more music will be released?
