What did you think the word “attempt” was pointing to here?
Since you somehow forgot how to scroll down:
4 revolutions in total were unsuccessfull
20 have lead to some kind of success (although not all lead to a “perfect” outcome, but they did topple the ruling regimes)
2 have no link and I am to lazy to google them
Also 5 DLC at a 20 $ Price point that adds only one extra subclass that isn’t balanced at all, a buggy alpha version on release day and of course the online servers will be shut down after a coupe of years ending everybody’s access anyway.
