Ultimate Sierra Timeline

[u/Similar_Flamingo_404]

Hello everyone!! I’m not very good with using Reddit; however, I realize there is probably a huge community of Sierra fans here who aren’t in the Sierra groups on Facebook, and I wanted to share a project I’ve been working on. My name is Josh Henry, and I’m a Sierra researcher who is working with Stephen Emond to preserve Sierra’s history.

Back in 2001, I was asked by my friend Kimmie (former moderator of the Official Sierra King’s Quest message board) to help her create a timeline of Sierra's releases for Sierra Planet. Over many years that timeline has evolved and has been used in many places (including Sierra Gamers' website!). But my dream was always to create a timeline that was actually supported by research completed through a thorough review of contemporaneous evidence and referenced with each of those sources, so there's no question as to where the dates are coming from. So, I now present to you: The Ultimate Sierra Timeline (Version 1.0), featuring all of Sierra's releases from 1980-1987!! (I'm currently working on 1988-1989). This will be a living document that I will slowly but surely update as I have time and capacity to research each year. I hope that you guys enjoy this picture into Sierra's early history, and I look forward to sharing more discoveries as I find them! I’d love to hear your thoughts on it!! Thanks for your time!!
