MonHun is the epitome of Acquired Taste. I bounced off of it hard, twice, prior to World being a thing. On the PSP and the 3DS. It's just very, very different than a lot of other stuff out there, and there's an enormous learning curve to each and every weapon type, monster type, and hell even the controls with the patented (crab) claw control style.
They've definitely made improvements over the years, and World is definitely the most accessible. But, yeah, nothing wrong with not being into it even if you've tried out each weapon type (or at least the ones that appeal to you aesthetically) and can't find a good fit/comfort. Obviously having friends you can play with would help getting over the hurdle too, and hopefully Wilds here supports cross-platform because World not basically doomed at minimum Xbox. Unsure how healthy PC is.
