Hooded Horse's terrific 4X strategy game Old World is getting another big DLC expansion set in south Asia

compared to other historical 4X games, I particularly like the orders system, which minimizes micro-management and late-game slog, and the characters/families/events, which keeps you on your toes as things are always changing both internally and externally.
it's been a while since i played Civ 4 or 5 but i loved them too when i used to play them!
