I'm not going to deny that simulationist tend to pooh-pooh game balance, but that's just one part of anti-game sentiment, and I'm really not seeing why I would have seen quite so much of it at various times if it was only amongst that group (which I haven't seen all that much of after the 80's--I'm not sure I'd actually run into anyone who was focused on it other than maybe on a societal level for decades until I got on this board).
You can go find it today, in force, on any board where older editions of D&D are favoured, and many (though not all) places where OSR games are favoured.
It's not hard. And no, it's not just "pooh-pooh"ing balance, it's an objection to any element that even smells to them like it's game rather than a simulation. But there is a weird double standard in that basically anything from 1E or earlier is fine, and not game-ish in the way is disliked, however little sense that makes. But it's not an even an edition-based sentiment - the quite a number of 5E players who feel this way. I've been coming across this the entire time the WWW has existed, so since about 1992/3.
(The one thing I have seen gradually "die a death" is the once-popular idea of "system doesn't matter", which even in 1993 seemed wildly erroneous to me, but which was once an extremely popular idea, especially when generic systems were actually quite popular, as they were in the '80s and '90s (GURPS, Champions, etc.).
There may not be a lot any more, but I'll flat out say if you didn't hit many in the 90's, you just weren't in the right places.
Sure, but where was it? Because it wasn't RPG.net or Shadowland.org for example. Nor here (albeit obviously the earliest forms of this place were in what 1999/2000?).
Sorry, but no. The people I'm talking about were anything but imaginary, and I'm frankly startled if you never hit any of them. I'm not sure I'd describe them as "sneering aesthetes", but they were a real and extensive subgroup at least at one time back when I was on USEnet.
Well I definitely wasn't on USEnet significantly, so sure.
Also, when was the last time you saw any of these people? 10 years ago? 20? 30? It'd be like finding a living fossil long thought extinct today, imho.
