Lets face it guys, even us fans dont know what next instalment should be. WW2 or maybe something different.
But how about…
REMAKING AoE 2 with todays technology instead? Add some extras like cards from AoE 3 to make each country unique in gameplay and thats it. Money will flow, really no need to look far.
At least I hope AoE 1 remaster outcome derailed your further remastering ambitions. Waste of time and resources.
