Yes, he said from the start - that you can end up in semi-harems (micro-harems), it's 2-3 girls, definitely not of them.
I don't think he would jeopardize his own game just for the sake of making it a harem, it will be against his own plot and lore - making some races who hated each others for decades members of one harem... nah.
Unless he couldn't bear with harems-whiners bugging him all the time, who doesn't give a shit about plot/story and just want the game to be a harem. That would be a pity.
