Small amount of women stalkers makes sense. There are women in the military too, or working as guards.
In theory, sure. Adventurous women do exist (Agnes Milowka and Noraly Schoenmaker come to mind).
But in practice, the likelyhood of running into such unique females would be next to zero,
unless the game writers created just such an unlikely scenario. And why would they do that? As fan service to feminist journalists or incel gamers? Neither are valid reasons from a lore/setting perspective.
IMO it adds to immersion to have a few female stalkers somewhere in the zone (as long as you don't go full retard with 50/50 ratio or make the girls always be best like Obsidian does).
On the contrary, I think female NPCs would draw too much attention to themselves by their mere existence (both the player's attention and from male NPCs in the gameworld). But Stalker is not about relationship drama, it's about the Zone. This is also why the previous Stalker 2 trailers worry me, with their dancing gay stalkers and (male) drama queens. Woke developers might then try to reduce the womens' distracting effect by making their personalities asexual and manly; but that would just draw even more attention to them, and in an even more negative way.
....
Here are the two ladies I mentioned above, I think both of them showcase true Stalker spirit (so it's not entirely off-topic). But should they be in the game? Absolutely not. Put them in Tomb Raider, Alien or Mass Effect instead.
Agnes died (a bit ominously) just a few months after uploading the video:
Diver calm to end as death closed in
Note Noraly's agreeable personality, in contrast with most "strong" women in pop culture that try to act tough to hide their insecurity. Highly recommended Youtube channel:
