I have an old physical copy of World of Goo and as far as I know there's no official way to update it to the new 2019 version. I was wondering if it should get its own page in the same way Sonic Adventure has three separate pages for its different versions. There's conflicting information between versions and it would get messy quickly trying to add notes everywhere.

I think it makes sense if the versions are significantly different. If there's not a clean way to integrate info on the two versions into a single article, feel free to create a new one.
