Nintendo has an advantage because they use older hardware and try to extend its lifespan far beyond when it should have been replaced. Once they had a system with long battery life and decent graphics (for the time) in place, they cemented the practice. This forces the developers to use as many tricks as they can to make good looking modern games while not having to adapt to modern hardware. Its like a cheat code for squashing bugs in games, but it comes with its own costs. They have a large enough following that they do not need to change. They also get to charge more than other competitors can sometimes. Still, they have some good world class games.
