Final Fantasy 15 is bringing its brotrip to PC, so we paid Hajime Tabata, the game director, a visit at Gamescom, finding out a bit more about modding, optimisation, and how the port is going to get PC players interested in the venerable series.
Even though several Final Fantasy games have been given PC ports, it’s still very much seen as a console series. Tabata and the dev team, then, had to figure out how to get players to associate it with PC as well.
