Main AC games;
2007 - AC1 - Male Lead
2009 - AC2 - Male Lead
2010 - ACB - Male Lead
2011 - ACR - Male Lead
2012 - AC3 - Male Lead
2013 - AC4 - Male Lead
2014 - ACU - Male Lead
2015 - ACS - Male & Woman Leads (male has 75% of main missions)

2017 - ACO - Male Lead (playable woman for 4 or 5 missions)
2018 - ACOd - Choose man or woman (man marketed more)

Women AC fans: Uuuum guys, how about a main game with a sole female lead?
Bad male AC fans: OMFG YOU ALREADY HAVE ONE WHERE YOU CAN CHOOSE ISN'T THAT ENOUGH JEEZ

If this won't put it into perspective for people who complain about #ACSisterhood , then.... well, I guess nothing will.

But as a developer I can safely say I wouldn't want such "fans" who totally miss out on the messages of the game to play them.
