Just a random thought, but it would be fun to have an aoe4 app.
I know that there already are some app to check the leaderbord and some to have some info on civs and build orders, but what I mean is to have a app that do a bit more.
Like, check the tech tree, more popular build orders, see the most recent patch or pup, but also link it to the account, see the civilization objectives, the historical facts that you can unlock in game with the objectives, and so on.
Is it pointless, I think that it might help people being more immersed in the game, especially new ones.
