I have paid someone to make a module, with that module you make your own module.
It is connected to another plugin called wishlist.
In short terms:
You can attack other users
You can make random attack
You can buy protection
I use the wishlist as a place you can buy a share, after a month there is a lottery whitch will tell whitch share will win. It is for now just a family game.
There is also to write your own module hwere you can decide what you can win, or what you lose.
Also ther are zombies attacking users. All is variable to adjust by admin.
My english is very bad.
I hope in some time to present it on a website in english, than you can look.
