Too Long; Didn't Read
The Switch is a family console, and happens to have a relatively low price point. Many of its best games still cost $60, however, making it tough to squeeze the most out of your wallet. Thankfully, there's plenty of cheap switch games for kids and adults that go on sale regularly.
For kids, games like LEGO Worlds and Cars 3: Driven to Win are currently on sale, bringing the price of each title to less than $10 a pop. For adults, they can go for other games on sale like Mortal Kombat 11, or for naturally cheaper titles such as Hollow Knight. And for the whole family, the classic Star Wars games retail for a very reasonable amount - or you can take advantage of the free games offered in the Nintendo Online service.
