I recall reading that Glennbo was a fan of DYO back in the day also. I was a big fan of the Schmittgens-Kibler DYO "system" that was published in The General - Vol 21 No. 1 I think. It was a bunch of tables that let you roll for front, nationality, weather, boards, VC, all the stuff Chapter H didn't cover. In a nostalgic mood last year, I updated this to include the desert and PTO and all the new boards up to 52 and sent a draft copy to MMP to consider for inclusion in The Journal. No idea if it will ever see print, but I still like the concept.
I just received in the mail today a copy of The Comprehensive Guide to Board Wargaming by Nicholas Palmer. It's a hardcover that was published in 1977. An interesting little book; there is a copy of SPI's giveaway tactical game Strike Force One included in the back cover, and Appendix C talks about the unit values (DYO) charts that Tom Oleson did for Panzerblitz. This would have to be the very first DYO system ever created for a tactical wargame. Palmer says of the system that "...this transforms the game to such advantage that no Panzerblitz player ever plays a regular situation again" (!)
What a difference from ASL, where the scenario designers have so much to choose from, and so much influence on who plays what. I look at PC games like Combat Mission which have large scenario design follows in the tradition of ASL, and even there, the use of random "purchase" scenarios (Quick Battles) seems to be just as popular as the large library of premade scenarios.
It's interesting that ASL's scenario designers have been able to stake such a solid claim and cast such a huge shadow over DYO. It seems to me that even when GI: Anvil of Victory was released, the lack of DYO values for American troops was considered a major gaffe because people really did want them.
