Sonic is basically what got me invested in voice actor swaps lol. I literally can’t stand some of the voice actor swaps in that series because they just sound so drastically different and wrong.
Voice issues happen a lot with anime too when it gets dubbed. Rarely will the dub be better, but there’s some iconic dubs like the pokemon cast, or haruhi. With the yuki-chan spin-off series of haruhi, I was really concerned they’d get different VAs and it’d be ruined as a result, but fortunately they had brought back the entire original cast.
I’d take it immediately. Whether it rolls back time as well, or just my physical/biological age, having that reset is good. For time, it lets me be able to jump on financial trends before they happen such as bitcoin. Also lets me redo some stuff I fucked up. For biological age it’s just regaining my youth and let’s me get on HRT earlier than I did which would’ve been beneficial. I kinda threw away the past 15 years, so having a redo would be nice.
