You have to wonder how many people you knew in this game, close or in passing, are dead now. Those specific users that always showed up in a public lobby same time as you and built a bond with, maybe you even made a clan with some of them. For me, their last activity ranged from 2014 to 2017 and if you never bothered to keep in touch outside the forums what's the difference between dead and missing anyways? I'll never know the difference.
People you knew during your most formative years and probably shaped your future in subtle and not-so-subtle ways all gone so you gotta ask yourself what is the point in coming back? For those who've grown out of the actual gameplay I don't there is.
