Minecraft has been suggested here but there’s also Minete St, free/open source version. The experience isn’t exactly the same but the basics are there. Works with PC and Android. You can also run one of the computers as a host and you can do multiplayer. Absolutely no microtransactions.

Time heals all wounds. Make sure you don’t keep reopening them.

I played so much X-Com, Civ 2, and Final Fantasy Tactics back in the day.

In this day and age they would be TikTok stars.
