MC has a harem throughout the whole game but ends up losing all of them, WTH??? Have I done something wrong?
A: No you didn't do anything wrong.
B: Realistically, Shit happens. And the real question is, how do you handle it when it does?
C: The MC doesn't lose them all. You have a choice of several realistically possible outcomes. Choose the one that best suits you.
Personal Side note: Reality vs Fantasy
Yes, you might have expected the ending to be a harem fetish fantasy, IE: "And they all lived happily together, fucking each other's brains out...sometimes in a pile, forever." Are you disappointed?
The fact that this Adult Adventure Sci-Fi story did not end in that impossible dream wish scenario is one of the major things that attracted me to it. It's more honest. The MC acts like an Adult at the end (responsible even though he's humanly vulnerable) and I think that speaks to the admirable and noble instincts within men. Life's
not fair. Harems
don't last forever. The ending shows a basic characteristic of the hero if he chooses his duty, resilience in adversity, or if he indulges in choosing one crew member, his lesser human side.
If you must have a fantasy forever ending, try "Greener Pastures" or other similar games. If you can see the truth that this game reveals maybe it'll help if/when you encounter similar personal situations.
This ending is more realistic.
