Well, again, Far Cry was also one of the first CryEngine games.
And CryEngine, when finally dead, still used 32-bit address spaces. CIG had to gut it and completely redesign it for their 64-bit addressing StarEngine.
Which has allowed for some sheerly amazing scale in their game. Literally a memory address for every square inch of the gamespace, which is a 1/6 scale solar system complete with orbiting planets that rotate and experience sunset and with PES, you can set a coffee cup on its side anywhere in game, leave, and come back a week later and that cup will be just as you left it if nobody else came along and grabbed or moved it.
And there are *very few* completed, in progress, or planned projects using 64-bit addressing, *still*, compared to games that are "64-bit" but still using 32-bit addressing.
