It may be worth noting that over at Replay games, Paul Trowe has an odd ego about him in that he believe s they are essentially Sierra 2.0. When the two guys from andromeda got back together and ran a kickstarter for their new game, Paul trolled their site and sent several disparaging remarks to the guy working with them (Chris Pope). The gist of it was - who are you and why aren't Scott and Mark working with me on this? Paul got so much heat from his antics that Josh Mandell replaced him as the "voice" of replay games, and now runs all the project updates and answers questions in the forums.
Paul is a trip. In his interviews with Al Lowe (and anywhere else for that matter), he repeatedly states he was the youngest employee at Sierra and talks about himself as much or if not more than he asks questions of others.
When Al Lowe worked with another group on their kickstarter game, Sam Suede, Paul sent them legal threats for claiming that Al was involved on their project... as though he had some sort of contract that prevented Al from working with anyone else. When Al made it clear he *was working with them (maybe Paul shoulda asked before all the very public legal threats?), Paul backed off... but not before permanently damaging the Sam Suede kickstarter and causing quite a bit of confusion among adventure game fans as to who was in the wrong.
All those attempts to get licenses from Activision were just part of his intention to get all the Sierra licenses again, and remake all the games (not produce new ones). Not that it changes anything in this timeline, but it gives some background on what exactly was going on there.
Nice work on the timeline Baggins.
