I want to make an MMORPG, but, seeing as the only games I've ever created were small Flash games, I have no clue where to start.

I need an easy beginner engine I guess to help me get the feel of it.

I have read the list at the top of the page and it doesn't really tell what is best for someone as nooby as me.

I don't really have much money at the moment so please only list free engines.

I have looked into Multiverse already but I don't have enough RAM to run it.
