Wow, people with caps are going to hate this. Whatever happened to games fitting on a cd or DVDs. This is getting out of hand.
I remember conversations 30 years ago that basically programmers will get more sloppy and use up whatever resources are available. The days of tight code are gone.
On top of it, there is a lot more overhead in 64-bit code than 32-bit code, at least in general.
While I agree that the days of tight code are gone, it's resources, and not the code. What's the largest program (that's at minimum compiled with the optimize flag) that you've ever created, excluding embedded resources? I'm talking code only here. As for games, no game should even be remotely close to even having a GB of compiled code.
