Fun thought experiment: whats the oldest game you regularly play? Whats the newest game you have 100+ hours in?

Kinda struggling to phrase regularly playing for newer games so... I guess 100+ hours in?

I think the oldest game I REGULARLY play might be Fallout 3. Honorable mentions being very rarely TES 4 and 3, and technically WoW as I play a lot of classic/vanilla content.

And newest game with solid hours right now is technically Raft. Though I'm wondering how early I adopted it before release... Honorable mention to Outer Worlds. And funnily, technically WoW, as I played a bit of War Within.
