Honestly, I don't think I can vouch for the quality of an educational MMORPG. I just don't think it's the proper format to pull off "fun and educational," since, let's face it, most of the people we meet on MMORPGs are idiots. Then there's the issue of trying to keep a paying audience. I just don't see it lasting very long at all, and thus people won't invest in it in the first place.
