Its not about being old...
Ignazzio , plenty of MC in some games are old, or not super handsome... but suspension of disbelief can only stretch so far...
If the dude was in his 50's like (Joel, James "our Fate", the tool protag from IR, the dad body fun guy from Midlife Crisis) people would be onboard... but when you toss a 90 year old man ??!?! I mean maybe some of them can still pop boners, but from the ones I been around can barely move their fucking legs, let alone gyrate their hips... no way in hell are they in "fucking" shape meaning they can actually have sex...
As for the Personal Assistant MC, dude is Lenny from Mice and Men, a disgusting creature you honestly dont want to see procreate and damage the gene pool...
