I hate that crap about people saying I only play OSR games due to nostalgia. Whatever. Yes, part of it is true, but I also think the rules are actually pretty darn good (though ascending AC is obviously superior to older AC systems). Ha!
Regarding nostalgia, I'm in my early 40s. I'm allowed to sit and read my old B/X or Star Frontiers books. They bring back a lot of great memories. Some of the best gaming I had was in my teens, and those were the games we had. If that offends everyone who screams that "Newer is better!". So be it. I don't care if you don't think older games are unworthy. They are perfect for me. So piss off.
