Keep it simple is my best advice. Use the tokens you already have that are inflating out of control to participate. Give every account 1 land upon reaching a set prestige with additional sales for purchase by burning shard/part. Make each land work well with your other plots so it will be more of a benefit to have 1 account over a dozen accounts. And, post regular updates for those who aren't on discord. Not sure what ever happened to the roguelike you were originally planning.

Quarterly seasons to keep the game fresh. Maybe different resources are better in different season. A tower defense style auto battler would be somewhat interesting and in line with the game theme. Ability to attach your golems to attack other players towers and steal some of their resources or damage their towers etc. Make it so dozens of players could get together to attack a higher ranking player so they can't just sit and farm. Guild notifications with an hour or 2 notice before a battle will take place so they can attach defenders to their guild mates to protect them but this may leave themselves vulnerable to attacks. Use the scouts in the game already to scout a towers defense levels for a set time period.

Ok, ill shut up now.
