Does This Game Have New Game+?
When playing the game you unlock achievements that give points to spend at character creation to buy traits for your character on that run and some achievements unlock more traits to buy.
As you unlock achievements periodically you add more attribute points to distribute at character creation. In game there’s a player house called a Homestead.
You can store legendary moves and legendary equipment there to pick up on future characters.
There is no newgame+ per se. But unlocking achievements would allow you to create better character which in return allows you to explore more content which would otherwise hard to access for your first few runs.
As for the Homestead mentioned above, think of it as a shared inventory between different save files. But the shared inventory has a lot of limitations to prevent you from duplicating items.
