Interesting. I can't imagine they're doing all this out of the goodness of their hearts. Wonder if they'll follow the cosmetic upgrade store, or something more akin to PokemonGO's monetization mechanics

The Verge article mentions an in-game currency (rupees) so I expect they are going down the 'in-game shop' route. With the option that you grind for the in-game currency or you can just swap real money for game money. Hopefully they wont make this pay to win and stick to just cosmetics. They have stated in the FAQ that they are not doing loot boxes so there is hope.
