It's a difficult thing to review an expansion pack for a massively multiplayer role-playing game that's so enormous it would literally take us months to explore each and every section of it. Square Enix's Final Fantasy XI and its first add-on pack Rise of the Zilart, after all, were already huge; and throwing in 40 additional areas spanning four all-new regions only serves to make it even bigger. But bigger is exactly what Final Fantasy XI: Chains of Promathia truly is, as it adds a considerable amount real estate compared to most enhancement bundles out there -- with storyline superfluities that are rarely seen in appendices of this type.
