MMORPG in Rails

Hi I'm trying to make a simple browser based MMORPG in Rails for fun.

One of the issues that I cannot resolve is how to architect several
universes. For example, go to and you will see that the
user can sign up to multiple universes to play in. Or kind of like WoW
where you can sign in to separate worlds. However for my game the
player is only allowed to ever play in the world he signed up in.

Would the best way to achieve this "partitioning" to create several
databases? Or is there a more effective way? I don't want to do it in
such a way that maintenance becomes a nightmare.


You are going down the WRONG path. This shouldn’t even be a question for you. Build your game, then if/when you need it, look into making multiple servers.
