EDIT: This post is satire, please be respectfull and share your ideas too.
Hire like 10 modders to update the game but keep an eye on them. Make them work for free and only give them in-game limited edition item and 50 more so they can give them to other ppl.
Then create a battle pass per update that increases gift and spool acquisition, with limited edition icons, limited edition drops etc..
Create a DLC and only allow player with the dlc to enter DLC-worlds. Sell the dlc for 10 bucks and you got enough to pay the modders that you used to create the dlc and updates.
Separate the team into groups, each group will focus on one thing only, like a skill tree group, a enviroment/map group, a combat/boss group etc..
Release updates 1 group at a time, making the other group have +6 months to work on their update.
Allow 2+ players access to a klei dedicated server and charge them for it.
Allow us to impulse the amount of event chests that we get even further with the battle pass.
Bring back forge and gorge as a DLC, and charge 9.99 for each and 14.99 for both. and 29.99 for both plus all future dlcs, but make it limited and promise us atleast 3 future dlcs.
