I have an i7-4790k and have yet to find a game it won’t play well, although I do tend to avoid the absolute bleeding edge when it comes to graphic settings. They were great CPUs and still are among the fastest at single-thread performance, which is what games care about more than anything else, while still having enough cores to not bottleneck on secondary threads.

As for game recommendations, both Cyberpunk 2077 and Baldur’s Gate 3 are recent favourites of mine with more replayability than their narrative would suggest.

For pure replayability though, nothing beats games like Factorio (THE FACTORY MUST GROW) or Kerbal Space Program (not 2) or Satisfactory, and basically any Roguelike/Roguelite. If you haven’t played Balatro go do that right away, it is crazy deep and will run on a potato.

Other games I keep coming back to and then getting addicted to for awhile for no obvious reason other than their replayability include regularly updated exploration/build/craft games like No Man’s Sky, Avorion, Astroneer, and Empyrion: Galactic Survival, Aska, and strategy games like Civilization 5/6, Stellaris, Crusader Kings 2/3, or XCOM.

Hope that helps!
