Honestly, Nintendo games keep their values longer than most, although I have picked up some good titles like Mario Galaxy 2 for $17 back a few years ago. However if you look at my post a few days ago (top of page 11), you'll see I bought Transformers for Xbox One and South Park Stick of Truth for about $22 total. So, prices can and will vary. They have a base price, which decreases over time until they sell out, and then they have sale prices where games they have a large stock of will dip into outrageous low prices (i.e.11.99 for Watchdogs PS4, or 8.99 for Stick of Truth) to drive up sales.
