And no, I have no relatives at Ensemble but still, I got pretty attached to this game studio for the amazing games they made over the years. I’ve been playing AOE2 since 2002. Barely touched MP but still find a ton of enjoyment with the game.
I’m not against architecture or unit sets actually, it’s just that I’m also a big fan of new civs
Kinda dissappointed that LOTW didn’t came with new architecture sets.
