I'm not going to say anything, because anything I would say would be a spoiler. Anything other than this: if this is a game you're considering, I would buy it and play it in a heartbeat. It is perhaps a better work of art than the original. I found the puzzles easier, but that's subjective and I went into this game coming straight from the Gehenna DLC. I say it's a better work of art perhaps also because it deals with current issues in its philosophical journey, while staying true to the original. I feel like if it weren't for nostalgia and cultural significance, the "Talos Principle" saga would top the Portal saga as a real contender for my #1 game of all time. Much like the Portal franchise, I think the second game is better than the first.
