Could anyone suggest some good strategy games (ressource management mostly!) Your help would be most appreciated! Also if someone could explain how to get friends that would be great!
Be active in the forums and sooner or later...^^
About the adding/finding/search friends side there is a handy guide in the newcomers sub.
Strategy Games... in a more general way TDs (like the GemCraft series, Kingdom Rush, Cursed Treasue, Mushroom revolution) are very good, also Battalion Nemesis and the Creeper World Series are on my favs list, but resource management... i would leave this task for other users^^
my top now are: Gemcraft and Creeper World as tower defence Factorio - the whole game is about building a factory and producing more and more complicated machines. Here a trailer: https://www.youtube.com/watch?v=9yDZM0diiYc
