It really didn't age well if anyone is getting that itch. The atmosphere is phenomenal but the puzzles can be extremely frustrating. Back in the day, that wasn't a problem because exploration felt like a privilege. Now, the scenery doesn't captivate like it used to and you just want to know how to solve the stupid thing.

Portal 2 is a great brain-teaser if anyone is looking for a constructive use of their time tonight. I recommend the Nyskrte NYS maps if you want a real head challenge.

The Witness, mentioned up-page (at time of writing—will probably stay there, given the author) is great and a bit Mystish, though with a very different sensibility re: puzzles. There's also The Talos Principle, which is kinda Myst+Portal.

I didn't like Portal 2's official single player campaign as much as the first Portal, but the two-player coop mode is excellent, and a rare example of multiplayer puzzling.

If anyone has that itch they can turn to Obduction and Quern : Undying thoughts, both recent and both very good.

My only problem with Obduction is the loading; oh my god the loading. I know they wanted to keep the original Myst on Windows 98 feel, but a 30 second to 2 minute load between scenes is killer and why I haven't finished it.
