TBH, even though I've never paid more than $20 for a game, I'd probably be willing to do so if it's a physical release considering I'll be displaying it somewhere, which's added value that digital games lack.

No more than $20 for digital though. I don't care what the game is or how much money I have, I'm happy to replay my favorite games and wait.

If you're selling for more than $20, you're probably a relatively big publisher anyway, and I don't feel obligated to pay what you're asking, or, in many cases, fund your mismanagement/feed your greed.
