Assassin's Creed games are pretty big, and that causes a problem that is almost unique to the series - fatigue. It may be down to the sheer length of Assassin's Creed games, how much there is to do in them, or the checklist-style nature of the modern games in the series running its course long before people roll the final credits.
There were some Assassin's Creed fans who hoped that maybe Assassin's Creed Shadows would buck that trend, myself included, but with just over a month gone after the game's release, that classic fatigue is beginning to kick in for a lot of people.
A Reddit user called Jymboh is one such person that has been hit with Assassin's Creed fatigue recently, who called it the "Valhalla syndrome" and, because of it, claimed they couldn't keep playing Shadows anymore. In their post, they admit that the world was able to "seduce me and maintain my attention", but that the map clearing a story had everything feeling "messy".
From a single trailer alone, I'm already more invested in Atsu's pursuit of revenge.
Another user called ContributionOk7429 describes "getting fatigued" in the middle of Act 2, disappointed that "nothing notable" happens...
