evidently, I can't seem to read English anymore. Let's check the schedule:
August: one bi, one straight, one gay, one straight content for a bi mission
September: one bi, one straight, one gay content
October: one bi, one everything goes content
November: one gay/straight, one bi, one everything goes content
December: one everything goes, 2 straight variants, one straight/gay unlocked content
January: 3 potential missions of which 2 gay and one straight
And then y'all have the gall to say that it's having WAY MORE gay than straight content planned! The nerve...
Let's be clear: this is one of the few games that are really 50/50. For each scene there are almost always two versions, one straight and one gay, with some bi thrown in the midst. This has been since the beginning and has never changed. So I can't really see this evolution you're talking about.
The only situation I can think there's an imbalance is Pandemonium, where there are 2 males and 1 female character (+1 futa). Although this is partially balanced by the fact that the LIs are mainly 5, 3 girls and 2 boys, with the third boy added only later and with less content.
Recently there has been a lot more bi content, thank you very much considering that week 2 is dedicated specifically to bi characters!
Not to mention that some content is chosen by those backers to pay a lot of money for the Psi commander tier (like the recent series of scenes with cousin Felix).
So, suck it.
