>>22339338>process the entire overworld at onceNot even that complicated. It's a cartridge based console, load times aren't a problem. Look at Zelda: A Link Between Worlds. No Load times/gates/ whatever in the overworld, everything's smooth.
Gamefreak is just incompetent shitty devs and we all know it. They can't even get battles with more than 3 pokemon to stop lagging lmao.
Well then again, to be honest, they have only been doing sprite games for years. But then AGAIN their sprite games didn't have amazing graphics either compared to other games in the same portables.
