Heres my Own version of How the Movie Timeline works with the AVP Movie And game franchise(Only the three major AVP Games Along with the Predator and Alien movies. And for most part it works without screwing any of the existing story lines.
Spoiler
The above timeline includes all movies and all three major avp games
Predator and Predator 2 are set in the late 80s to early 90s. So this marks it first in the Conntected timeline, Then Comes AVP Movie 1 and AVP Movie 2 which are set later in the timeline around the year 2000(Forgot the exact date) Because of the Plasma caster found in AVP2 the Wayland company pushes forward space travel. So now Alien begins where Ash having his orders by the company to protect the alien and to get it back(we all know that the company already knew about the aliens existance by now.
The next event happens 57 years later and the Aliens movie storyline begins. However at this point the theres two known timelines. The AVP comic and video game timeline where Aliens are still at large and the explosion didnt take out the crashsite(But it still took out the Hadley's hope). In the Official
Movie cannon where it did and the events with alien 3 proceed like normal we move onward 200 years to the end of the Known Alien story.
Meanwhile in the Game universe. The wayland company is still at large studying the aliens(Seen in Game1) After that happens AVP2 Game happens and then AVP3 Happens(Bishop is in AVP3 so the game happens slightly before or after the third alien movie.
Ok so my Second timeline is AVP only and works better if the Alien Movies and Predator movies never happened. So it starts in this order. AVP Movie 1 then AVP Movie 2 you Jump forward into the future and Game one starts and then after that game two followed by game three.
Then The Third movie begins around the time of Marines and Aliens and Predators. The third movie is a fresh reboot set in space. After that the New movie is followed by a sequel and then one more sequel to end it off. The Comics are happening around about after game 1 and continueing still after game 3
