Hi folks,
Just thought I'd chip in with a few of my own points fo view on publishing D20 Modern material.
Our latest product, Modern Heroes: Martial Avengers is a D20 Modern supplement. We have been designing and writing this since we first got hold of D20M in the first week of its release (or at least as soon as it came out in our local games store here in Blighty). So, one aspect is likely to be turn around. Publishers usually have their schedule booked up 12-24 months in advance with products they're currently working on (I know we do!). Add to that that they're also going to be sceptical about how well D20M is going to do and how much of a market there is likely tobe there for it. I don't think the market is as big as I had initially thought it could be. Unfortunately quality is no guarantee of success in today's market, otherwise I think D20M would be doing a lot better.
Secondly, I think that when you're writing a complete setting, such as WW did with Adventure, I think (as mentioned already) that you're going to your basic game usable with D&D rather than D20. This is just simple economics. That said, I think publishers can learn from D20M and as a result produce stuff that fits in a lot better and is much more easily convertable. For exmple, our DarkLore game is a dark fantasy game, with the basic characters a little bit powered down from basic D&D ones, but with added versatility which comes from using ideas we learned from D20M. We have 6 very generic base classes which use talent trees to determine their powers. On top of the advantages in terms of feel and flexibility we feel that this adds to DarkLore, it also means that there are new talent trees that are very easily integratable with D20M. This way you can add sneak attack to your fast hero, or wizardly spellcasting to your smart hero. Charismatic heroes can gain some paladin-like powers of desity. Tough heroes can gain some ranger abilities. Obviously these are all quite fantasy oriented (well, DarkLore is a fantasy game, but should the flavour fit you can use them in D20M).
This is a design criteria we're taking through to our upcoming Etherscope game. We're designing 6 basic classes which are in many ways like the 6 D20M classes. However, as with DarkLore, we felt it was important to resdesign these classes to add flavour to the setting. With them I think we've really managed to get a 'best of both worlds' approach.
Cheerio,
