I know this blog isn't about philosophizing or opinionating, but I'm going to say this anyways: I don't like the sentiment that gamers are "turning back" to "OSR" games.
1 - If the OSR relies solely gamers that started with 0e-1e games, it will fail. Period. Full stop. Those young hooligans that so many grognards seem to relish disdaining are the future of gaming. Suck it up.
2- You can't "turn back" to something you never experienced. See #1. A 16-year old that discovers the joy of a vintage car isn't "turning back", he's discovering something.
3- the phrase and sentiment "turning back" implies a linearity; that game design proceeds from simple to complex. I don't believe that. It might -appear- that way, but at this point, 0e and 4e aren't two versions of the same system; they're functionally two different systems, with different strengths. Playing 0e isn't "turning back" any more than playing True20 is.
