entitled to his opinion and all that (though he should be thrashed for his choice of font imo). One assertion that always rears its ugly head in these debates is that OSR players play the old games often for reasons of nostalgia.
Is it nostalgia? Do you get a sense of "the good old days" when you play B/X or AD&D today? Do you find yourself recalling those glory days of yesteryear in your Mom's basement?
I just don't have those moments really.
Occam's Razor suggests that those of us who still play, or in my case devolved back to playing, the older games do so primarily because we prefer those rules. Since it's usually the DM in the group who is the straw that stirs the drink if you will, I think that there is simply a percentage of players, that is to say DMs, who enjoy the experience of running the game using the old rules. It really is quite different than running 3.X or 4E and I think the new 5E design team would do well to consider the "DM Fun" aspect of old school gaming. Take 0E for example. I thoroughly enjoy running a good session of Whitebox. There's absolutely zero nostalgia factor for me with Whitebox since it predates my introduction to the hobby by about 5 years. There are no memories to rekindle and it is entirely the same for all of the dozen or more players with whom I've played Whitebox. It's simply a very liberating framework of a game for the DM and it's quick and easy to learn.
And finally, how much does the burn out created by grid-based combat, particularly in the case of the guy providing the grid and running the baddies, factor into ones desire to move back to earlier modes of gameplay?
For me, this is a very big deal and I suspect I'm not alone here, though it's pretty clear that I fall in the minority (as a non-Pathfinder, non-4E DM). I think one of the flaws of 3.X style gaming, and 4E really gets carried away with this, is that your game becomes overly focused on the use of the 5-foot square grid and the miniatures. This leads to lengthy combats, which again, that's a feature for folks who dig that mode of play. But I also think it can lead to burnout and in my case, that's a large part of why I still like the old games. They don't grind me down as a DM and I have more fun running the game.
