Some people in game development talk about a shift from programmer-centric development to ‘content-centric’ development, which happens in the early 90s. i.e. while in the 80s it was feasible for a handful of programmers to do all the code, design, art, management, etc, in the early 90s games start becoming more content-heavy, such that design and art constitute the bulk of the development process, rather than just programming. So game companies had to start establishing ‘tool chains’ and ‘pipelines’ to not only manage and discretise all these separate components of development, but also to patent their development processes. So I dunno, maybe a flashpoint would be something like the DOOM engine in 93? Though that seems a bit late.
But yeah, agree w/ @BustedAstromech that you probably want to think about separate markets, and also separate regions. There were plenty of pirate-based industries in operation well into the 90s around the world.
