So, there are a ton of MMOs out there, and I've tried a few, and I don't like any of them, because:
-They rarely have a living world that your actions have any real effect on.
-Before you can do anything interesting you have to spend hours, or days, levelgrinding.
For a while now, I've been thinking about making a forum game set in a world where whatever you do has realistic consequences, and the players are free to do whatever they want (sandbox style), but goals should emerge naturally. There a few things the game should have:
-Ability to have lots of players.
-A simple system for controlling the characters.
-Ability to easily deal with players being inactive.
-As few NPCs as possible - the players should be the driving forces of the world.
-Any role should be available to a player when they join the game, anything from a lowly civilian to an adventurer to a ruler of a nation.
-There should be a living economy formed by supply and demand.
My current thinking is a medieval-fantasy-style world, where the game takes place in a wilderness territory. Players can try to build their own empires, or get whatever job they like in someone else's domain. There wouldn't be any real turns, instead you post your action and as soon as the GM has posted the result you can post a new action. The world would be divided up into a number of smaller regions, with natural resources tracked for each of them.
I hope the above text made any sense. What do you think about it?
