For those who may not watch Nappy's other content, he went on a nice little rant at the start of his Dark Rising video today.
(alluded to above, but here's the actual video)
If you skip to about 7:35 though, there's some relevant Reborn talk!
Nappy says that one day, he'll go back himself and Nuzlocke Reborn because it's a "great game" and he "wants the challenge".
I really do think he loves this game, deep down.
