You can easily play them on GeForce Now, for what it's worth. It just streams to a browser window (or an app if you prefer). There's a free plan, or the higher-quality monthly plans are under $20. https://www.nvidia.com/en-us/geforce-now/

You might also the enjoy the Talos Principle games, which are also on GFN.

And the first Dungeon Defenders game has a Portal Gun tie-in (it's tower defense, not a puzzle game, but you can make portals to send mobs into lava or whatever).

Oh, the thought didn’t even occur. Pretty wild that these days one can stream 3D games. Gotta try it some day!

Yeah, it's pretty crazy how far we've come. A decade ago, we had OnLive and it wasn't a very good experience, Stadia failed, etc., but these days there are a whole bunch of game streaming services (GFN is by far the best, for the games it supports).

Anyway, have fun! I wish I could play through Portal again for the first time.
