Seastone are pretty barebones
Not to mention yes the differences between Alpha and Beta
Now before I go on, I should mention that even in tits I never had an issue with content distribution (as this debate is older than both games).
But just like in TiTS, judging distribution by raw NPC count has always been misleading. NPCs aren't created equal. While there are more females than futas in starhome, one is asexual, one has a solo scene, and the other is locked behind a foursome that also involves a futa.
In regards to content for futas theres:
Evergreens new blowjob
Dragoon Azzy and Dragon Evelyn, Seastone's myraid of scenes and the futa shark(s) down there, (technically Futa Lyric), Kas dungeon scenes (admittedly only three), The water bard, technically the dragon mace, Vivianne got that new scene, technically Berwyn, Arona's got a bunch of new scenes + that pregnancy expansion, and uhhh... Well we're not counting dickgirls right?
When did those undermountain demons get added?
There's seldom been long periods where futa lovers haven't been eating good.
Edit: Actually now that I think on it. The only people who really have been starving are male lovers.
As per usual, really.
