There are hardly any free MMORPGs Out there.
Try Gunbound however,(yes, Gunbound is considered an MMORPG)u can download it for free at
www.Gunbound.net
If u r into a complete MMORPG experience, try Runescape. I for one hate runescape because of its aweful graphics and reppetetive gameplay, but i guess that might work.....
Its hard to find good RPG's nowadays, everyone is trying tyo do the same thing...
I recommend gunbound though, they really think outtside the box.
