I agree. But RPG part is not focus, at least in AoW3 and Planetfall. It was in AoW1, but just because there was no random map generator/city building and you had to play campaigns.the rpg aspect of any age of wonder games always was strong. it was always about one leader who level up, clear dungeons and loot items while managing his empire and his army.
and each empires had its own alignement.
