Realmcrafter.com is the right website to go to. This forum has seen thousands of threads, and post on making an MMO. Keep your ideas small and build on those. Don't think you are going to beat out a game such as World Of Warcraft, Ever Quest etc. As a hobby game developer Realm Crafter will give you decent results with little time. However, the developers arent really involved in the community anymore, and a lot of there programs remain broken. Mostly the community are the ones fixing bugs now. The developers made a broken Engine, and kept it that way. Eclipse is great for 2D MMO's, and has a great community and lots of help. Good luck.
