As im going down the route of using GameMaker Studio (It allows windows/phone/console) builds
We could of used the existing Era Server if we wanted but made no sense to do so.
So currently. The client Connects to a GM built server and just logins.
Im currently importing the original GRHs files and editing them to GMs transparency and combined the Tilemap files into one pallet for GM use.
I have done some modifications to the original map editor to spew out the map file into something else for me to use in GM.
Next few weeks will be loading a few player bodys/heads/weapons and getting them to draw together and move together, then will be coding the movement to be validated by server and sent to other connected players.
