I like the idea of a community-owned gaming system. I have played a number of systems in my time, often favoring something over D&D. I ran MERP/Rolemaster over 2E. I have even done some (very amateur) game design. That said, what it comes down to for me--and I realize others do not see it the same--is whether with a particular system I can run the game that I envision. I don't play other systems just for the joy of playing multiple systems as many do.
Since it came out, 3E/d20 has been my system of choice because it has enough simplicity and flexibility to run the game I envision. That is not to say I think it is a perfect system. In fact there are a number of particulars that I am not in love with. Vancian magic being the top of the list. I am a convert to Elements of Magic as that fits my vision of magic very well. In fact I had spent some time trying to devise a similar system, but more universal. (Meaning no spell lists, just combinations of elements and forces.) But that was too complicated so I gave it up. I also like the Sovereign Stone d20 magic system, but having to learn a new book of spells was too intimidating.
I like the idea of a VP/WP system, but when I tried it in my D&D game, it slowed down combat so it lost the intensity that the simple HP system allowed. But that's something that could be worked out and perfected by a community.
So to me, more interesting is the creation of adjuncts that can be used along with d20. Another thing I would be intersted in seeing is a classless alternative. Or a "Classless" class which would use XP to purchase skills, feats, spellcasting, improved saves or BAB. Something that could be integrated into the system I use, but that would have a community effort in creation, evaluation, and playtesting to ensure each adjunct would integrate and balance properly with the existing rules.
I like the idea of having the Linux of gaming systems, but as I see it we have the SRD and that is an open and preexisting framework that can be built upon, so I would be more interested in something that allows me to draw on both the commercially-available and community-created materials. Especially given some of the quality work that's being published and the sizable investment I have in it.
I know that's not really an answer to your question. It's more of a long-winded non-answer, but I guess it's my community-input which can now be freely considered or ignored with no self-congratulation or bitterness from me either way.
