Things I liked and didn't. Combinations that worked well and others that seemed forced.
Also how do you call it an All Girls Harem ending without Nicole?
Best ones are probably:
Sis, Ash(cousin)
Sis, Vic
Nicole, Sis
Nicole, Ashley
Ones I didn't like:
Kristina/Twins (The relationship was just a fling so it was only you and Kristina at the end)
Sis, Jaz (like a rewritten version of the Victoria-Sis ending and a third as long)
Nicole and Vic (he literally just reused the dream for the most of it)
On to the next game. If he follows pattern, the next one will be incest free.
