You can post an [Idea] thread for your project if you have a reasonable idea of what it's going to be like. There aren't many requirements for posting in the Progressing Games section anyway, particularly for [Idea] threads.
Just go ahead and post it, and I'll look it over before approving it.
So I am in the early stages of development for my own Pokemon game and was wondering if it would be okay if I posted it in the progressing games section even though it doesn't meet all the requirements. Thank you for listening ^.^
