Where am I wrong though, point it out. Will he have content himself equal to all 3 female MCs combined, or is he just leftovers to try and convince male MC fans to play this game when they could be playing something else?
You are speculating at best and plain wrong at worst. You haven't played it, so why guess? Just play it. Aden's prologue has 73 unique images. The other girls combine for 56. Not quite what you thought, is it? Oh, and Aden so far has the most dialog of any character at over 400 blocks of dialog. The next closest is Stheno at 387. Not everything is written yet, but I'd say the game's writing is about 80% complete.
