Definitely very fun when playing with friends. Unfortunately most of my friends don't really care for this game and playing alone is definitely a lot harder, but still fun.

The world is really big and it can be a bit annoying and boring travelling the sea when you're trying to go somewhere and it takes several minutes to just get there in the first place. However, there is no shortage of things to do. You can take on the basic quests from the outposts to get quick coins, but that gets repetitive after a while. You can then do the longer and more lore-focused tall-tails, which require more time be invested when playing. You can also fight the raid bosses and world events that occur randomly.

All in all, fun to play. Definitely play with friends if you can, though.
