A solid puzzle game, it's hard to not get reminded of Portal 2 while playing it due to some shared mechanics such as pressure plates, cubes and lasers, but also some writing and aesthetic choices. That being said, The Talos Principle leans way more on the philosophical matters surrounding AI and its implications for humanity.
I think the puzzles are generally good and the developers stretched the available tools to an impressive degree. Some of the puzzles near the end of the game require precise use of the available tools in order to succeed. There's only one tool I didn't really like because it requires standing around doing nothing.
On a different note, I believe the writing is highly competent, but the interactive elements are rather limited. Many of the questions the game presents to the player during interactive segments have a multiple choice format which is good for machines, but not so much for humans. There's a reason why teachers often also ask students to justify their answer in written tests.
As a result, I often felt like the consequences to my choices, so to speak, didn't really matter to me on a personal level because the answer I gave didn't really represent me to begin with. Although I can see the trick working on other people and it's an interesting read regardless.
Overall, I would say The Talos Principle is pretty good. It's an easy recommendation to anyone who enjoys puzzle games and it's a lot more cerebral than other titles in the genre, or video games in general.
