Oh I missed that one. Now that's the one I wanted to see. Really incredible work.
I'm also making a timeline on the events of the alien-predator universe, not like an official one of course, since it has a lot of EU stuff, its more like my personal canon timeline, just for a hobby, I'm actually enjoying doing it a lot.
I don't go as detailed with the dates as you are, like you even puts the dates of birth from all the characters!
I'm more into detailing the events that happened in the movies, comics/novels and games, more into history rather than the characters. I'm one of those fans that tries to fit the EU I like within my canon, so I was searching for more info on the dates of some comics/novels, well some will end up a little different from yours since I try to place the stories in a way it doesn't contradict itself with other stories that much lol.
I still have lot to do, I kind of stopped over the last years, I had finished detailing the events on AVP2(game) and was starting to add stuff from the last novels I had read at that time, like South China Sea, Sea of Sorrows, the Rage War. Now its going to take a while to research both the old stuff plus the new material that was released since last year and then write everything down.
Well good luck with your research, also I noticed you didn't put many of the games in the Banned Histories, if you ever need any info with the dates and the events that happens in them I can help.
