I would advise being very careful about going on a spending spree to avoid an illusory loss. Owning a game doesn't mean you're going to play it, and the vast majority of games on PS3/PSP/Vita are just less refined, graphically inferior versions of stuff we have access to easily today. Classics that stand the test of time are usually remastered and re-released with very few exceptions, and there's always emulation for what falls through the cracks. Think long and hard about what you'll actually get around to sinking the time into playing. Wanting to preserve opportunities to play things is understandable, but ultimately misguided if it's an opportunity you're spending money on that you'll never actually utilize.
That was a hard lesson for me to learn... For one, I obtained over 1000 games on steam in the last 10 years and maybe 100 of them are ones I should've bought. Not to say there's no one that going on a spending spree before the stores shut down doesn't make sense for, just make sure that applies to you. Don't let FOMO dictate your actions.
Paying the cash for a game is only part of the process of consuming it. The other costs are time and patience and those are steeper the older you get.
