In trailer of anniversary update you can heard from BBQTurkman " We are making AoE II bigger than it ever was ".
Making AoE II bigger is not balance changes. There are many things that we don’t know. They showed only new civilization picker, Battle Royale mode, Empire Wars on ranked and thats really all.
In game data recently 3 new campaign files were added. 1 have 6 empty folders ( 6 missions ) and other 2 have 5 empty files ( 5 missions ).
I really hope for Lithuanian campaign too ! The campaign against Teutonic Order.
AoE II is set in medieval age, but yet it lacks the biggest european medieval battle - Battle of Grunwald 1410 where Polish-Lithuanian forces crushed Teutons.
