Personally I feel like you could still change REALITY.fla to be it's own thing.
The enemies (as far as I can tell) are completely unique to the animation and haven't shown up in the official canon at all.
The same goes for the intro scene.
You could easily make it into something strongly resembling the official series but with your own twist on it, which I think would be the best option for it.
The work you've got done on it so far is way too good to just be discarded.

If it's close to completion, you could probably just dump what you have finished on your own thing or you could pass it off to another GP member to slap a bow on it and call it done. Would kinda suck to have something with that much dedication be scrapped away.

I could also always finish it at a later date, but I feel as though I hyped the cartoon up to the point where it won't deliver if it came out.
But it's also not entirely about hitting satisfaction with others, and the workload left on it isn't enough to sway me from completing it as is.
It's entirely possible I could finish it within the start of next year before finally digging into Miami Madness or this newly proposed Cyberpunk themed project.
