I just end up keeping one Nintendo Switch game (or two at most) and just sell one for another game so I don't always have to pay 59.99 so I can just go ahead and pay $20 - $30 instead of 40/50 for a new or used game. The only downside is if I have to go on a long trip that's what I'm stuck with playing and occupying myself with for the next few hours depending on where I'm going. Its been bugging me recently as well because while the 3ds was out I don't think it was common to see games priced at 59.99, normally at most they were around 19.99 - 59.99 depending on the title.
I think at launch Mario Kart 7 was 39.99 and Super Mario 3D Land was 29.99 or 39.99 I might be wrong on that though.
If your really desperate to play Nintendo Switch games, look for indie games that are typically 9.99 - 19.99 *cough, Minecraft, Terraria (I think?), Retro City DX, Pacman Museum, Stardew Valley, Slime San"
