I mean, for one, I can understand not getting into it since it's a very boss battle focused game, something that I can understand not everybody is going to easily get into, and two, Monster Hunter was mainly a Monster focused game, so it makes sense the focus is mainly on the monsters than the characters. While it did have characters with distinct personalities and they worked for the simplistic story each game had, almost none of them had names and were mainly called Titles like "Moga/Pokke/Kokoto/etc Chief", "Guild Sweetheart", "The Caravaneer", etc. It took until Monster Hunter World(Somewhat) and Monster Hunter Rise to actually start giving characters names.
That said, Monster Hunter is definitely on my top list because besides the cool monsters that can appear as cameos and Monster Hunter having a ton of potential for moveset with 14 different weapon types and a ton of items and gear for utility, the other two reasons are the music, easily some of Capcom's best soundtracks, and the big thing I'm pretty sure alot of other fans are hoping for, the possibility of each costume being a different Armor Set. And also hoping for a Felyne/Palico Assist Trophy.
And also wishful hoping, I'd be all for a Hunting Horn item(not the Hunting Horn weapon) that acts like a Pokeball for Monster Hunter that calls a random Monster to the arena to start wrecking players(including the one who summoned them, since the whole point of the Hunting Horn item is to lure a Monster to the player for them to fight) and the stage.
