i play mainly solo, game's great. there are only a few items that are multiplayer-only, like the totems that lock down building in an area, or the cartography table. everything else is available and relevant to a solo player.

a small note is that hunting sea serpents was always a favorite of mine but since they rebalanced the harpoon stamina usage, its definitely more difficult to drag onto land as a solo player. with 2 people alternating harpoons, it would probably be a lot easier.
