While Portal 1 was basically originally a side dish in The Orange Box and does gets overshadowed by most other games in its universe, I still think it is a really good game and a amazing foundation for something bigger. While the game is really short and simple, it is also extremely innovative and well design, with the portal gun being one of the coolest thing ever. The pacing is extremely solid. Game still looks and sound good, like all the Source game Valve as made are truly timeless. The writing is fun, especially toward the end, even if still pretty simplistic, but the added Rat Man room do help build the world. This game, along side probably Super Mario Bros 1 and Doom (1993), is what I consider the standard on how a good game should be design and a game everyone should play.
