Lots of old assassins games available for PC for about $5 each so it looks like the Microsoft rumours must be true and they will all be on game pass soon :p
Assassins creed
Assassins creed 2
AC revelations
AC brotherhood
AC black flag
AC Rogue
AC freedom cry (I think this was a PlayStation exclusive at one point)
And the 3 chronicles
There is also an anime bundle which would be great if I knew any of the anime’s
