But if hackmaster is included, I do not see why Fading Sun, 7th Sea, L5R, and ESD aren't included.
My return question is:
Are Fading Sun, 7th Sea, L5r or ESD d20 products or based off of AD&D?
If any of them have an answer of "Yes." then they should be included. If all of them aRE "No.", then I would have to say you are trying to compare apples and oranges.
Since any gaming product based off of either d20 or earlier versions of AD&D will be fairly similar in many ways, then these products should be considered to be of at least passing interest to a d20 gamer, since they will show alternatives that are viable, and fairly easy to implement, for their games.
Anything that is not either d20, or AD&D based, obviously does not belong on a d20 forum.
So, to continue in this vein, d20 CoC should be included, but not original Chaosium CoC. d20 SW should be included, but not WEG SW. And so forth. Although the examples given could be argued the other way as well, since the non-d20 CoC and SW product could be of use to a d20 game of the "same" genre.
HackMaster is a third generation AD&D product, similar in many ways, despite the arguments from those in both camps, to AD&D3E. Each product developed the earlier AD&D material in a slightly different direction, but they both have items of value, benefit, and utility to the "other" camp.
Just a few thoughts to ponder. For both camps.
