This game actively hates you and wants you to go outside.
Are you gonna take that?
I honestly think this is the BEST one and I feel that the underwater combat kinda helps it?
Most of the other MonHuns have you just choose a weapon and make you gain profficiency as a player with it for the entirety of the game, Tri I feel was trying to make players branch out and try new weapons depending on the situation?
Like faster enemies would be better with longsword / SNS, fast attacking / underwater enemies are better fought with something that can propperly block like with Greatsword or Lance etc.
The monsters really require some dedication and trial and error to seriously get good at. Enemies will absolutley stun lock you given the chance and you need to be able to determine when those attacks are coming, how bullshit the hitbox is gonna be and when you should and shouldn't use items.
Items are also way more strictly obtained, you're always going out to collect recourses for potions n honey which really set in stone that these recourses are FINITE.
Also the day/night cycle is something I really miss, Enemies are harder at night and drop more but in the day they're weaker so it's better to learn their moves then.
All of these points are for one major theme that I feel is lost in the future games.
You are a HUNTER. Not a ninja, weathered explorer or any special hero. All of your achievements are your own. And all that shit is HARD to do man..

also this game has like, really nice art.
