Yeah, 15's a bit too excessive. 7 or 8 would absolutely be believable, though, if you had versions from across multiple generations of consoles and maybe also counted SE, AE, and VR.
Yes, everything else is kinda like some people really write, but 15 copies immediately blow the bit, they should just say their copy (well maybe 3 since it's Skyrim after all).
Volcel gags aside, most chuds go out of their way to mod away the "subhuman" characters in Elder Scrolls games while shoving in naked deformed conspicuously childlike cartoon characters instead.
Wouldn't be a Bethesda game without being keep alive for almost a decade and a half thanks to coomer brains and white supremacists doing power fantasies.
There was a somewhat recent drama where (you do not, under any circumstances, 'gotta hand it to em') Nexusmods actually did strike down a mod that removed the vanilla ability to gay marry NPCs, whereafter I believe that modder took their shidding and crying doodoo ass to Loverslab where even they were like 'man come on'
So it's a bit but there are people in the fanbase like that unironically still
