@Gothix i agree with you in all points, but not every API is a bad one.
In my opinion once the game is ready, there could be some space for thinking about possible API access. I am thinking here mostly about social features. That can be some online indicator per example. But as said, too early to think about.
For sure i don't want to see the features @Woniken requested for the API, except the price one (2.) ... but again, nothing to talk about, before we don't know anything about how trading will work and which tools we get ingame in our hands.
As for the Linux Port... there is no need for, because it will work in Linux.
Sometimes i am really ask myself, why people are so less interested into the few important informations on the Game Page, like the FAQ and Design-Journals.
