for a porn game , aigis at least had decent gameplay , a somewhat decent story (with events that were related with each other) and was decently noob friendly , with gold/plat/black units being all usable.
I enjoy kamihime , but make no mistake , as a game , i find it way weaker then aigis. Heck , even the main storyline seems incomplete. Not that aigis was complete (we never got all eastern missions , or magic city , or jungle on our version) , but at least the creators were releasing new mission maps outside of just events.
