Of singleplayer games, it may be Quake. This one was created before the recent remaster and compatible with different engines.
In honor of Quake’s 20th anniversary, MachineGames, an internal development studio of ZeniMax Media, who are the current owners of the Quake IP, released online a new expansion pack for free, called Episode 5: Dimension of the Past.
Episode 6: Dimension of the Machine was released in 2021. Quake was released in 1996, making it 25 years.
I have a feeling there’s probably some obscure-ass Nethack clone that’s been getting regular updates since the creator first programmed it on a PDP/11 but outside of that I can’t think of any actual commercial products that have received expansions that long after.

Sigil doesn’t count, but it should.
