Was about freaking time to make this list.
Rank is recommended order to watch I found on some site.
Added date is sorted chronologically.
Personally I'd watch the first two movies first, then SAC, then Arise.
But actually it doesn't matter that much cause the first two movies are their own universe, The Stand Alone Complex is its own universe, and Arise is its own universe, tho as far as I know it's better to watch Arise at last.
We will ignore 2.0., Arise Alternative Architecture, and we will definitely for sure as fuck ignore the live action.
The 2045 show did not got much good ratings so far, as I didn't watched it yet, maybe it's something to ignore in the future too.
