And I sure hope it was worth it (I did the Oath patch)! I'm pretty sure most people have finished Oath in Felghana by now, but I really wanted to do this, and it simply ended up taking a much longer time than I originally hoped it would...
It perhaps doesn't help that finding an unused stage in an old Mario game simply isn't that exciting due to the way Mario stages are themed rather than completely distinct. The stuff that could be out there to find simply isn't likely to be as as a Wood Zone or a Hidden Palace Zone, unless we were to find scrapped levels in a prototype of a more modern Mario title. Unused content is always interesting in its own way, but it's the big mysteries surrounding Sonic unused content that really made me invest myself in the Sonic scene back then, and I'm sure that's true for a lot of people.
