Hello everyone! So far there are very few sources of information about Endless Space, with links scattered all over the forums so I thought I would group them together in one thread for new comers to the forum to see. Plus after Gamescom I'm sure there will be quite a few articles with information pertaining to Endless Space 2 floating around the internet and it would be much easier for everyone I think to have them all grouped together. So I hope that you find this list helpful and if anyone finds a link not on the list feel free to post it and I'll update the list.
