Well, not just art. We need art, and also scriptwriters, and coders, and a whole lot of other things. The most important things are going to be music, backgrounds, and sprites for the actual game, but other than that, there will also need to be a team of skilled writers. I have been in this fandom since it started, and I've always wanted to make a fan-game for it. Please know that this is a volunteer position as I legitimately have no money at all. I still want to make my dream come true, though, and I won't be making any money off of this anyway.
Please do be warned that this does involve fanchildren, fanmade children of canon characters. If that bothers you, please don't say anything.
If you're interested in helping out, great! Let me know here, or ask me for my discord.
