I like the idea, Onag, and I might just do some things if it gets off the ground.(busy with a dutch site and j2o v2 right now, so I don't know how much I would do)

I think you're one of the only good programmers in the community, Roaster and PaG are not here anymore, so for the code you would hope some people not from this community would join in, or people would learn to code. I know some C++ basics, but I never felt like really doing something in that language, but I guess I could learn a lot by watching the code, and maybe contribute something.

About the Planet Mechaius idea, I am skeptical. I'd think it would be fun if there was a combination of natural forms and technical forms, like in Jazz Jackrabbit, instead of mostly technical. What happened to your marshmallow idea?

Perhaps another dimension of the Jazz Jackrabbit world(put in smart references to that world) where the turtles won, and conquered all worlds. You'd have turtle bases, tree-house turtles, or something like that.
