Portal is one of my top games of all time and I'd recommend it to anyone. The core of the game is based on a series of testing rooms which you progress through using a Portal Gun, which allows you to create two ends of a portal which you can pass objects and yourself through. The dialogue and voice acting are genuinely funny, the portal mechanics are original and work really well. The story is the perfect length and it's extendable with community made puzzles. It's also aged really well and still runs perfectly on modern hardware 10 years later. An absolute must-buy for any gamer anywhere.
