I keep trying to do so, a few years ago when I had Game Pass I got to the Citadel and was trying to read all the lore then dropped it. Bought a copy of the trilogy on PS4 and will prob play that one of these days. Only things I know are the original ending to the trilogy came in 3 colors, and Suicide Mission OST is top tier. Going in blind otherwise.
Yes, it's weird as fuck. If you have any nostalgia for old web pages it's an excellent experience. For everyone else it's a quirky ass time capsule puzzle game/text adventure. Definitely worth experiencing.
If you really want to like it, and enjoy the concept of what the game is trying to do, push onward. MH has become one of my favorite series, but I nearly dropped it and dismissed World as trash after spending my first 10 hours overwhelmed by all the bullshit tutorials, the wacky menus, the clunky gameplay, and how you are somehow expected to read and understand all of the mechanics.
Also, what weapon are you using? The contextual attacks are very much like a fighting game for some weapons, and I hate fighting games. But I love Smash Bros because you have simpler and more predictable attacks you feel more in control with, and MH has some weapons that you can play that way until you get comfortable with everything else. This is a game you don't want to try and learn everything at once, you need to learn a couple ways to deal damage and then the game loop for a while, then you begin to add in one new move that you previously neglected.
It's sad that the game still needs this, but a youtube tutorial on how to play and the basic game loop is probably the best way to learn without anyone that can directly teach you. You will be doing things without knowing why, through rote memorization at first, and then figure out all the details later. Eat --> Hunt --> Craft --> Restock Items --> Eat is the loop.
What did you assign the back buttons to?
