/vr/ - Retro Games

What is the highest amount of money you have paid for a retro game?

Personally I wouldn't spend over $100 for a retro game. I own a couple factory sealed games I bought like 10 years ago that might be worth some money now, I only paid $20 a piece for them.

I'm really not comfortable shelling out a lot of cash for one game. It makes me wonder what kind of security is in place to prevent counterfeits. Do these 20+ year old games really remain hard to counterfeit? I imagine people are pretty good in modern times at recreating labels and making high quality fakes.
