The great thing about games that are 10+ years old is that they're cheap, you can filter out all but the best rated, and the hardware to run them won't require mortgaging your first born.

I'm building a Steam library for my retirement.

I quit gaming when I had kids, and currently play tennis and do inline skating as my regular active hobbies (which, I believe, count as touching grass), with gaming as my injury / infirmity backup.

Agreed, part of playing old games is that you aren’t required to be exploited by hardware manufacturers who are charging exorbitant prices for GPUs and RAM. A constant whine I hear is the unaffordability of hardware to play new games, but you do not have to play new games. For the cost of a single GPU you can fund many other hobbies for a lifetime.
