Assuming there will be more.
I think the game needs way more Gaia wildlife and textures for map making and a functional online lobby the most. We have lots of South East Asia civs but very little in wildlife and "non shallow water" textures so campaigns that just happen to bring a diverse set of tools for mapmaking would be great. The online lobby and main menu needs a complete remake it's truly horrible but that doesn't really work as a DLC so it will probably never happen.
