-Release 3.0, 3.5, d20 Modern SRDs into CC but also 1e, 2e and 4e (and OGL for the new ones).
-Add all 3.5 content (minus IP of course) to the 3.5 SRD.
-Add them all to ORC as well because why not
-As for my pet project, get in contact with those who designed and wrote Fiendish Codex 1 and 2 for 3.5 to see if they can or know someone who can write the 3rd entry in the series detailing the Yugoloths. All this will be done for 3.5 of course.
-Get a new CRPG game in the works using 3.5 rules. It'll be realtime with pause but with the option to switch to turn based like the Pathfinder CRPGs. Best of both worlds.
As for 5e and 6e/OneD&D/5.5 eh... hire someone to manage that and yeah whatever. Don't care. I'll just stay in my 3.5 bubble and pump out more sourcebooks for that. Maybe a Celestial codex? That'll be fun.
