December 2023 Update Info | Phantasy Star Online 2 New Genesis Official Site

I posted a comment about the game before here. The game has improved since it launched, but if running around grinding for hours to improve your gear at the endgame doesn't sound appealing then you most likely won't enjoy it still.

The game was designed with solo play in mind but later content is much easier if you play with other players. There is matchmaking so you don't need to work about making a party ahead of time.
