nice effort. You could use TRAC or Redmine to manage the tasks.
Anyway you should define some points:
1.- Opensource or not?
2.- Target platforms (real Amigas/MorphOS/AROS/OS4.x)
2.1.- if the target is making a game for real Amigas would it be AGA or ECS?
2.2- What would be the minimum cpu configuration?*I ask because it's not the same doing a game for unexpanded A500/A1200 than an AGA+040/060 game.
3.- Free or not? I mean: is it a real company to make money that will have revenue and will pay salaries to its workers or is it a join effort to make games?
4.- Depending on the number of coders I would advise to use subversion/git to make working together easier. If just 1-2 coder per project it's not really mandatory (although with 2 it's more comfortable)
5.- Quite a lot of years ago there was a mailing list for game creators, I remember Yssing and me were in but I can't remember who was the administrator, perhaps he can write a short email to people who were in the mailing list to see if they have interest :-)
6.- Is the plan doing "portable" games that will also run on other platforms like Android/iPhone so some money is won? More or less like it was done with Fortis (MorphOS version is free).
