No.1 an auction house where u can put in an item and select a prize anf other players can come here and buy it for the prize ( money goes ofc. To owner )
No.2 a pvp arena : either 1vs1 or/and a part for team pvp . Also their could be a prize for the winner or a bounty on someone who has a spree ( few (3) wins in a row) also u shouldnt allow taking pots somehow if thats possible
No.3 i can imagine that this is hard to implement cuz of so many players ft has but maybe a little house for everyone as storage room u can buy (i know there are pets but thats not a real safe storage cuz they can die and need to be transported ) or maybe a main building with many little cells with chests in for everyone so there is more space than in overground city .
... and ofc lots of shops and crafting stations .
Pls let me know if u like the ideas.
I hope they get implemented cuz these are thr things i miss the most in this mmorpg.
U can also add ur own ideas here
