The Witness from Jonathan Blow made me buy this game. I had absolutely no expectations, I only bought it because I had read they were similar, and The Witness is set to release later this month.
Turns out The Talos Principle was one of my favorite game experience ever. I rarely play puzzle games and even when I do, I usually don't have the patience to try and solve/search for everything. But Talos caught me really fast. The way the game teaches you stuff is amazing. You are exploring a world filled with puzzles. You solve those while using tools and get rewarded with sigils. Eventually you will unlock more tools and more worlds with those sigils. And maybe if you get enough, you will be able to understand the beautiful world you are trapped in, because all you really want is to escape, right?
The game also contains hidden stars. This is where the game is really at, where the challenge is. You just can't beat the feeling you get by discovering 'how' to get and solve some of those harder stars. They are also dozens of easter eggs everywhere and those are all about exploration of the world, getting out of boundaries, being clever, taking a leap, being innovative and you get rewarded really good sometimes.
Most puzzle games have little story or not at all. But yet, Talos got me into it's story more than RPG games such as Dark Souls. You have those metaphysical conversations with a terminal. They get really deep. You end up questioning yourself about your actions, choices, who you are and what you believe, humanity in general, so much more too.
The music is quite relaxing and really amazing. It fits the theme really well and it didn't took me long to realize I might have to buy the soundtrack too.
I bought the DLC Road To Gehenna to get me some more puzzles. Talos also made me buy Portal 1 and 2.
