Hopefully some people on this board do, but I agree I think a lot of people don't.I don't really think people realize what he meant from all of that. If you go back to road to PS5 there is a chart where they were Targeting reading 2GB in .27 Seconds. Yeah. This basically can allow for some crazy stuff loading game data.
The concept of a memory limit is baked into basically every game we've all ever played. The storage speed has always been too slow to load new areas or new items in real time... So every game has to load them ahead of time.
Hence every game has levels, from pong loading one set of bricks at a time, to tomb raider hiding the level load behind a zig zagged corridor.
It is genuinely a very different way of building the very concept of a game. How to do you factor in the frenetic bits and quiet bits if you don't have level loads? Where do you put score screens or even show scores? How do you give the player natural rest points or save points?
