Armored Core timeline

[Roh]

I'm just curiose how many of the games could be connected in someway? I tried to come up with a time line. (I had to read up on some of the earlier games so correct me if I'm wrong)
I'd like to find out more about the main aspects of the story lines Human+ , A.I's , Dominants , etc etc. and their possible connections if any?.

time line
AC 1
AC PP
AC MOA (first 3 games probably just a few years apart maybe decades)
67 years later events of AC2
5 years later events of AC AA

the first 3 games all have a place called isaac city
AC 2 is stated to have occured 67 years later
AC AA is stated to occure 5 years after that
______________________________________________________

new time line? , another layered? , events that took place at some point durring the 67 years in the previose time line? (probably early in the 67 years)

AC 3 events of the game and leaving the layered
AC SILENT LINE newly on the surface
AC NEXUS settling on the surface
AC NINEBREAKER training during the peace that was brought by the corporations merging?
AC LAST RAVEN clearly a continuation due to characters in the game being the same as in nexus
