So, while this site was down, for LEGO Island's 20th anniversary (Oct. 2) I tried to organize a Reddit AMA with people who worked on the game, as many as I could contact and would be interested. I got in touch with a number of people, ~12-16 iirc. Unfortunately, the AMA ultimately never materialized, mostly because an AMA requires verification, and I didn't know how that could happen for such an old game. (Then the r/games mods got peeved at me for being overenthusiastic, basically saying I'll never be able to try to do any AMA there again.) And during that time, Wes Jenkins passed away (about a week from LI's 20th anniversary original release date, iirc), which basically sealed the "not gonna happen" deal.
However, as a result of my contact, one of the animators wrote up an interesting article on his time working on the game (he emailed it to me, and I saved it in this document just now) - https://docs.google.com/document/d/1chL_iGfo-h559vnR6ds_ZDnLWicZ48RYxFlf1wmV2aE/edit?usp=sharing
EDIT: Talked to Kathleen "Brick-by-Brick" Salvia, very nice lady.
