The Title Says It,I would except any Final Fantasylike game but

the www.fantasy-mmorpg.com one.

their's Myth wars. It's not exactly 2D but it kinda looks like a painting. It's turn based, though it has no customization.

There's also TS online, but i think it's dead....not sure.

You won't find any MMO's like FF. Not even FFXI is similar to the other FF's.
