I'm gonna make an assumption that you aren't a classic monster hunter veteran - if you are, this game is great solo and has lots of fun stuff you would remember.

Otherwise, this will be a game with a ton of content but extremely grueling learning curve playing solo. The game is perfectly fine solo for a large part (ie 300 hours), but there is some endgame special hunts that require you to be good at videogames, or play multiplayer.

Overall great game, but this is a send-off swan-song for the classic monster hunter series.
