Quoted from pin2d:

I didn't know Lyman well, I had met him a couple times and been to a group dinner with him, and we corresponded by email occasionally. He was always super nice and engaging and interested in others. I don't have any crazy stories but here is a mini-story I thought was interesting.
On TWIP I used to do an "interview" called Around the Playfield with ____, a very low key laid back format that had no personalized hard hitting questions, just stuff like "what is your favorite pinball machine" and "how did you get into pinball" and questions like that. I ended up doing a bunch of them with a lot of different folks in pinball.
Only ONE person had any revisions to his/her answers - Lyman. He sent me responses, then the next day said he reviewed them and sent me version 2. Then the next day he said he reviewed them again and sent me "V3", which at that point he said "I promise, now, like the code for Walking Dead, it is done Done DONE!"
We joked about all the changes he kept making, and he shared that he tweaked the HORDE mode on TWD a bunch too to get it right (one of my favorite modes in all of pinball). I felt like it was an insight into his perfectionist tendencies with his code. Just a cool nerd-out moment for me in the hobby. RIP Lyman.
