Absolutely fair, hopefully we can produce a finished product that you'd be willing to try out in a few years. As for ATU, I may come back to it every once in a while to do some minor clean up on some parts, like making certain scenes more grounded but I highly doubt I'll have any drive or motivation to actually improve it in a noteworthy way. Nothing that requires a replay of the whole game.
To me, I'd rather spend my time working on the NEXT great project instead of trying to salvage (in my eyes) a big mess of scraps, clunkily put together with super glue and glitter. I'm happy just having it sat in the garage as an occasional reminder of where I started from and that it gave me the experience to create better things.
I think most people, if asked to instead of working on a new, exciting project that would be better than the last, they should try and improve the work they did 10 years ago when they were fresh faced, green, and learning the fundamentals. They'd scoff at the idea, it just doesn't have a single appealing aspects to it. And that's not towards you specifically, I just mean in general, we sometimes forget how soul-sucking backtracking is, in art, games, work, life, whatever. Everyone wants to feel like we're moving forward and not back.
I appreciate you having ranked ATU so highly on your personal favorites, I wouldn't even rank that game in my top 20. Which is good for me personally, it means my standards for a game I can create is still sky high.
