If I had to show a non-gamer what games can be, I would probably show them Portal 2. This game does absolutely everything right, and I simply can't recommend it enough.

The gameplay is buttery smooth, the puzzles are wonderfully creative, the soundtrack is amazingly atmospheric, and it doesn't just stop at the single-player campaign; it even features a whole other co-op campaign to play with a friend. And if that's not enough for you, there are even community-created test chambers that will challenge even the most big-brained individuals.

What I can say about the campaign without going into spoilers is that it's, like the rest of the game, simply timeless. The characters are all so wonderfully charming and extremely memorable that even on multiple playthroughs, they make the game a joy to play. The test chambers are a blast to figure out, and it always feels rewarding when you finally get to the end. On repeat playthroughs, they might not be as intriguing since you know the answer already, but I have always waited enough time for my repeat playthroughs for them to not grow stale.

I wholeheartedly recommend this game to pretty much anyone, both new to gaming and veterans. It's an experience you won't forget.
