They look like the kind of games I'd enjoy. I think I wound up adding most if not all you recommended here. And broke down and created a Steam account since i could be here a while and need more options. Heck, if you're just into adventure or puzzle games in general, I can make you a crapton more recommendations on top of those. The Schizm series required you to be a Menza member to solve The Light House was the first puzzle adventure I played. Prominence (extremely well-designed first-person adventure game) The Painscreek Killings (detective-style game, requires you to take a lot of notes about the things you read) The Talos Principle (haven't personally played, but heard good things about)

If you don't mind using Steam, try one of the following:

Frogwares' series of Sherlock Holmes games (basically anything that says 'Sherlock Holmes' on it here on GOG) Lighthouse: The Dark Being (Sierra's answer to Myst)

Schizm: Mysterious Journey (haven't personally played, but similar style) Return of the Obra Dinn (not really a first-person adventure/puzzle game like the others here, more of a detective thing, but absolutely excellent) The 7th Guest/The 11th Hour (very cool B-movie horror atmosphere with these, although the puzzles leave something to be desired and the games really need a facelift) Timelapse (not the greatest puzzles here, you basically already played the best of the genre, but still decent)

What you're looking for are adventure games with environmental puzzles.
