Which has nothing at all to do with this thread!
These days and on IMac I play, Forge of Empires, several years now. But on old PC I loved "Hitman" and Castle Wolfenstein, wish I could get them now. Never had a true games console. What would you recommend for a total beginner?
Asking "which console should I get" is likely to start a flamewar

If you have children I'd recommend a Nintendo Switch but the PS4 seems to have a good lineup.
Alternatively, you'd be surprised at what games you can get that you can play on Macs.
While their Mac library isn't as comprehensive as their Windows library is, Steam (
https://store.steampowered.com/ ) has a decent selection of games that run natively on Macs.
GOG (
https://www.gog.com/ ) has a good selection of games both old and new (it's where I got Dungeon Keeper from), some with native Mac versions, some that use a program called DOSBox to get ancient games to run on modern systems (this will let you run them on a Mac with no configuration).
Finally, if you don't mind doing a bit of reading and getting your hands dirty you can often run Windows games using Wine (
https://www.winehq.org/ ) although it's not 100% guaranteed that a game will work, but they maintain a database of games that do work with test results for different operating systems.
I tend to have more success using Wine to run games I got from GOG than those I get from Steam because GOG puts work in to ensure that older games that are prone to compatibility issues can run on modern systems, which seems to help.
