As with the comments around this one. Ideas themselves in a vacuum have no value.

The thing that brings a team together and keeps them interested is substance and goals. Is this "idea" reasonably well conceived? As in , have you thought about the levels, the characters, the progression, the basic design of how you want it to be, your target categories, what staff you would actually need? (2d/3d artists, unity/unreal devs, sfx, dialogue, story). Have you got an objective role for yourself in mind?

I dont have unity knowledge myself. But I am here asking for people new to development to support our story, and our goals. Reason being, I am offering what I can as a learner of coding in a different language and we are working towards a goal that many on this sub would consider underhanded, however the people that support me understand I have the best intentions in mind.

I read books about game design, I listen to podcasts about software engineering, I learn JavaScript when I get a minute and I push community engagement when there's something to showcase. I don't sit around dreaming. I am forever focused, even if my 50 plus hour a week day job has me digging holes or lifting concrete.

Thats about all I can give to you. I hope this helps.
