Now that you mention the older games you own. It might be worth it to make some backups in the form of iso’s or copies. In case they get disk rot at some point. I think some of them must be close to 30 years old now.
Funny you mention Strife. I never really knew about Strife until much later when I found out about it. I have played the shareware version of Heretic quite a lot. But what really fascinated me back then where the early Grand Theft Auto and Carmageddon games. I guess my interest for cars translated into my games as well. Since those are technically open world driving games beside other things.
