Make it so players can change the play area.
Like what you said, building bridges and whatnot.
And mining, say, you can find new ore veins that get opened up to everyone, or in a forest you find a tunnel that now everyone can use ect.
Hmm, so when it is first opened, have many undiscovered areas, and as it is played, new areas open up? That sounds very unique, but what about when the server is closed? Should the areas be closed back up?
If you want to make a succesful RPG, make bots that aren't zombies, because I want to battle a swordsmen, not a zombie. Also, make up some skills. Make your RPG unique.
Yes, I do not like using zombies in RPG's, so I will be trying to make battling bots using Amade's bot events.
I gave a exp system in my rpg however somehow it screwed up because now my variables are vce how do I get rid of vce variables mod?
You don't get rid of them. You learn them and move on.
