Imagine a girl you like putting a hand on your shoulder, looking into your eyes, saying some gentle word I don’t quite remember due to being mesmerized by those eyes, and you know what I did? I just looked back uneasily for a few seconds, then nervously took her hand off my shoulder, shook it a bit, released it and awkwardly smiled. (That even wasn’t her last attempt to make me happy against my best efforts ; ended bad anyway.)
There are many things further down the road to go wrong with attractive popular girls. 2 most catastrophic cases in my life are with those such as them.
Admittedly I’m the one who mainly failed them due to misunderstandings and passiveness, but when a girl (being all that popular) is used to boys being rather active and competitive and social, and then you are here just cause she happened to like your looks, this may end painfully, for you more than for her.
There are also cases from the post, only I may have noticed, just wouldn’t risk losing an existing good friendship for possible romance.
In some sense this would even seem an advantage of Windows. (I know it’s the fundamental reason for many hangs and freezes, but the idea that a file is a lockable resource doesn’t seem that bad.)
Some even Paradox ones. One can waste many-many hours in CK:DV with Mappa Regnorum mod, for example. Though CK2 is more complex, it lacks the relative simplicity and clarity.
