Yes.
Ian isn't terribly interesting (though not entirely generic), but all of his partners are very different from each other.
Lena is very customizable in her looks and corruption, but most of her partners are just dicks (except Robert the gigachad) and what matters is the effect they have on her.
it's true, ian suffers from the "i'm a protagonist, i need to be a blank canvas for the player to imagine themselves in" problematic. however from all men in the game he has the most depth, so i can't agree with your assessment. especially since alison and cindy are also somewhat shallow and emma is decidedly shallow (though that may change if she wants to get serious with ian).
Because just like in life, women get everything handed and served to them on a silver platter just by asking but men have to work and fight. Lmao
so you are saying this porn game wants to emulate realism? porn games. games which every 2nd is a harem maker and incest is a form of greeting?
seriously though, in my experience and what people i know did, a ffm threesome did happen way more often than a mmf. and it weren't the nobody guys who got chosen. (though maybe me and my old friends experiences are not representative for the whole world)
It's not so much that men as a whole are used interchangeably but more that Eva does it a lot with specific characters. It's been done with Ian-Robert-Mike-Mark for a while and now John is added to that list. They all have lighter skin and similar base builds, as in height and width where Eva can change them slightly to account for hair, faces and muscle differences.
I assume the reason Eva does this is to pad Lena's M/F roster somewhat, though she did use Axel's scenes for Jack too.
The women in Ian's life seem to vary more in height and build. You could conceivably copy/paste Holly, Cherry and Cindy for each other, they are similarly slim though I think Holly might be shorter? As for Lena I actually think the woman with the most similar body to her is actually Jessica.
that could be. though i think i remember a axel scene also got used for ian and they don't really have the same build. besides this scene:
should be really easy to change the woman to whoever.
i guess i can understand that if the schedule looks something like "thursday evening the FMC needs a sex scene and i have 2 men who fit the bill." it does make sense to shorten the workload by rehashing frames. that way you can quickly do casual scenes, as the writing needs to be simple, and put more effort in more important scenes. but it shouldn't be any different if the genders are reversed.
for example cindy is very similiar to lena. to the point i caught myself calling her "the blonde lena". if i were evakiss i would have already used a cindy scene as lena and vice versa, either with axel or with ian. it is just advisable if i'm already rehashing scenes for the sake of having less to do.
