I’m speculating, and certainly not a business expert, so heaping handfuls of salt comes with this statement: I think part of the problem that led to this is that each game was published by a different entity. Square published 2016, then put the devs up for sale the following year, citing underperformance. IO buys itself out and becomes independent, but needs capital to get Hitman 2 across the finish line. Enter a publishing deal with Warner Bros. That game proves successful enough that Hitman 3 is able to be self-published.
Considering IO’s concept of this World of Assassination trilogy was always that it would have certain online-only or live servicey features, and I assume that publishers often provide the necessary infrastructure for these things, I wonder if the rotating chair of publishers is to blame for making this process so much more obtuse than it needs to be.
You’re doing good work.
