Take Call of Duty®: Ghosts, another multi-generation game that numerous developers, including Farrelly, Harris, and Hagar, remember creating. Nearly a decade ago, Ghosts had its own water-based Campaign mission: “Into the Deep.” Because of the technology available in 2013, it was well out of scope to create realistic water physics and graphics – along with, of course, that infamous Fish AI – while still having the technical resources and memory space to have the rest of the game run at the Call of Duty standard 60 frames per second.
