When making the Thimbleweed park game, they kept a blog.
Its decent and has some interesting tidbits on how they designed the game. I read after I played through to avoid spoilers, but it was a fun game.
I don't have a link handy, but there is a "monkey island 1 ultimate talkie" version of the original Monkey Island that I highly recommend.
My understanding is that someone backported the speech from the remastered version into the original game. So you can play the original MI1 in SCUMMVM, with speech. It's great.
Maybe it's just nostalgia, but I prefer playing the game without the voice acting.
It's a bit hard to describe why, but there's a lot of both dry and surreal lines in the game, and hearing Guybrush deliver them all in the same bemused voice can get a little monotonous, and makes the character come across differently from just reading them.
If you have an original copy you can run it with ScummVM: https://www.scummvm.org/compatibility/
Ron Gilbert and Gary Winnick made a new game in 2014 too, it's excellent: https://en.wikipedia.org/wiki/Thimbleweed_Park
