I figure I might as well jot down these ideas before I forget...
The RPG could be setup so you can have different Neighborhoods
. Where some are more expensive to live in and owen a business than others.
A random Crime Act
(robbery for example) could be built in... Depending on the neighborhood you live or own a Business in, will determine your chances of being a victim. Naturally, the more expensive neighborhoods would decrease your chances of becoming a victim of a Crime.
When members first join they could either automatically be Homeless
or it could be setup so they are automatically in Public Housing
(in the least expensive Neighborhood).
Another "rule" could be that you cannot purchase a Home unless you have a Family
(which you have to purchase).
These are just ideas... The whole point is to keep your members returning to your site, keep them engaged... and of course for you and your members to have fun. Of course, the Mod have to be written first
