My girlfriend is a fan of the old point-and-click Nancy Drew games. Nearly all of them are sold on Steam, and while some work fine, others won't even launch or have immediate breaking issues. We discovered that the games run better (granted, not really well enough to actually play them..) on Linux via Steam Proton than they do on modern Windows.
I have had much better experiences with gog.com instead of Steam for old games. They tend to actually make sure something runs before putting it up for sale.
Might be worth checking out for you. Though I see only one Nancy Drew game there.
