I am fully aware FFXI has a small budget, however it also has a dedicated fanbase.
If you cannot fund things outside of basic running costs and basic updates, why not attempt a kickstarter project to allow us to give the developers money to make things such as an expansion?
If a community manager sees this can you pass it along and see if the developers are open to the idea or if Square would even allow such a thing? It's a shame to see how little money 11 has for new content, when it has a very passionate audience of players willing to support it more if it means we get more things in the game.
