skyrim required more ram because of crappy coding, not because it was physically required.
you can hide crappy code and bugs by adding more ram sure but at its core its still flawed. bethesda have a reputation for awesome games but also for not fixing their **** before release and sometimes after release as well.
they admitted it needed major work to the engine to fix it fully and to simply release it knowing the work needed doing but neglecting to do it is no excuse and to blame it on system memory is a joke
anyway lol ill stop ranting about bethesda im still pissed that i lost approx 50hrs play on 360 and on ps3 due to game killing bugs where i literally cannot carry on without starting a new game or going back to a real old save but the ram is not everything.
coded correctly for systems and not just porting over in a rush is the real solution and i hope that developers actually acknowledge it this time around and make a winning console
