Depends on what crash you're talking about?
A crash where retro games will flood the market and loose a ton of value?
I will be catching up on everything I had a hard time affording. lol
I started collecting because love of the games/art/history, not value.
If your talking about what happened in 1983 and people stop buying new games and game companies struggle to stay afloat. While I don't think it will hurt me personally to much. I'll still be collecting and buying games.
Biggest worry I have is once they faze out physical copies. (yes I know the companies are going that route)
But once it does It just means I can focus more on the games I missed and I'll only be buying a few new games a year just because I want to play them bad enough that I'll download the game. (maybe wait for sales)
I know one thing for sure, the minute they go 100% digital they will be loosing a ton of money from my wallet.
