Old, but relevant:
http://gamerescape.com/2012/07/25/ga...012/#more-3967GE- In North America Seekers of Adoulin will not be available for the PlayStation 2. Can you tell us what lead to this decision? It seems a bit odd to increase HDD capacity for the game on the console then only release the expansion in one territory. Why not release the expansion digitally?
SE (Answered by Square Enix, Inc.)- In evaluating the North American release of the expansion across all platforms, we needed to consider multiple factors, including the number of players exclusively on the system, and the costs associated with publishing or developing a stand-alone download. Regrettably, these two factors greatly determined our final decision to support the PC and Xbox platforms exclusively. However, we remain committed to supporting FINAL FANTASY XI on the PlayStation 2 platform for the foreseeable future.
