Sierra was both a publisher and a developer led by husband and wife team Ken and Roberta Williams. The first Leisure Suit Larry came out in 1987. Sierra didn’t acquire Dynamix until 1990, and they had nothing to do with Larry. Dynamix was known more for flight simulator games like Red Barron. The only forums around then were on Usenet and BBS’s. I used to run one of those BBS's. Fun times!
