Are you angry about the location or the language, because the Scandinavian sites are all still in EN/DE/FR/JP depending on what you select. There's no native language option for them yet.

I think the crux of the matter is that whereas Spanish is the second most-spoken language in the world, the most-spoken languages for FFXIV players and prospective FFXIV players are EN/DE/FR/JP.

Once presumes that either the ES localisation team are hard at work, or that S-E have surveyed the market and seen that the number of additional ES players they could bring in would not be worth the cost of a localisation team and the changes they would need to make to the game databases.
