And some of them are nearly as succesful as that Blizzard thing, what was it called...^^
The good thing about MMOs and A7 is that you dont need great graphics to have a chance in the competition; Please correct me if Im wrong, but afaik there is no MMO currently on the market, except for AoC maybe, that got graphics that A7 cant recreate with a medium amount of work. So theres no problem with that.
