Thought y'all might find this interesting. Some will look at this and see it as a good sign for the OSR. I suppose it is. I'm still not entirely certain, however, how you make an entire campaign out of "Tomb of Horrors." I suspect that you build a bunch of dungeons and other such out of a backstory for Acererak. I just can't help but feel it will widely miss the major point. ToH was written with a certain mindset, one that becomes clear to players who are careful and observant and who take their play seriously. Like "Vault of the Drow" and "Shrine of the Kuo-toa," ToH is a blatant repudiation of the stereotypical kill-and-loot style of play. Can you build an entire campaign out of that theme? Especially in 4e? Is the skill challenges system now robust enough to take the strain of supporting a campaign? Hell, is it strong enough to support an entire adventure? Especially considering that, last I heard, they're still built around the assumption that the players will fail more than half of them?
Of course, that still misses the point, since ToH embraces not rolling dice. Heck, even its most infamous trap doesn't invoke dice, even for a saving throw. I doubt WotC has the cojones to build a D&D campaign that is focused on not rolling dice. But I'll be first in line to buy it if they are, just to see what it looks like.
The world of Hard Fun, er, I mean, "Dark Sun" is, of course, not considered something "classic" in the strictist sense, being very much a product of the era of 2e. It is, however, quite pulpish and pleasantly twisted, and a very fitting contribution to our Year of Science Fantasy. I still regret not picking up the original, and I'm curious to see what WotC does with the setting.
