Pros
Pro Great storyline
The puzzles in the game are great, but they're tied together with a thought provoking story line filled with mystery and intrigue. A story about a robot with human consciousness who is being guided by a disembodied voice, are they to be trusted? As the story progresses the player is drip fed clues which can lead them closer to the truth.
Pro Lots of side content
Many Easter eggs and more difficult puzzles as well as an ending in many parts of the game, as well as hidden lore.
Pro Difficulty ramp-up
Starts out easy enough, but gets to some truly difficult puzzles by the end. If you get stuck on a puzzle you can skip it and come back to it later.
Pro Rewards exploration and out-of-the-box thinking
It's hard to explain this without spoiling anything, but there are lots of "aha!" moments you will encounter on the areas if you get invested into the story, making the game deeper.
Pro Great original soundtrack
The soundtrack is very pleasant to listen to and fits perfectly with all the areas and themes present in the game. It varies from calm music, for those heavenly areas where you are solving puzzles, to more misterious and epic pieces for moments when things get... real. It's good to have some nice music playing while your brain is melting from solving the puzzles, or just appreciating the scenery.
Pro Requires solving spatial and physics based puzzles using portals
The main mechanic of the game revolves around solving different puzzles using a handheld portal device - a device that can bend space and time to create a wormhole through which you can move.
Pro Humorous telling of a dark story
Portal is known for its humor. Even years after it's been out in the world people are still quoting and referencing it in everyday situations.
Pro The game leaves clues to a deeper story
Throughout both Portal games there are hints left in various forms that fill in more of the story, including information about Chell's personal history.
Pro Innovative gameplay
Portal has won multiple awards for innovative design. Using a first person view and portals that allow one to traverse a room through one placed in one location to the other placed in another location to solve puzzles was and still is a very unique game design.
Pro Created one of the most memorable characters in gaming history - GLaDOS
GLaDOS, or Genetic Lifeform and Disk Operating System, is the main antagonist of Portal games. She is voiced by Ellen McLain with the voice later processed to sound closer to how a text-to-speech program would synthesize a voice.
GLaDOS initially functions as a guide to the player and is only later revealed as a manipulative, narcissistic, sinister and passive-aggressive character that wants to kill the protagonist.
GLaDOS is the main force that moves the humorous yet dark narrative of Portal series with her remarks being simultaneously hilarious and terrifying.
Pro Character-driven
Even though the only organic sentient being in this game is the player's character, this game features some of the most memorable and intriguing characters in fiction or in gameplay. GladOS obviously, but also the drone robots that sweet-talk the player to a sudden death (and then forgive you when you dismantle them), the clues left behind by former test subjects, the abandoned hints of what the lab used to be like. It tells a story without telling a story, and immerses you more than most other games can ever hope to achieve.
Pro Made people fall in love with an inanimate, virtual object
The game made people emotionally attach to The Weighted Companion Cube and feel uncomfortable when later forced to incinerate it.
Pro Merges first-person shooting mechanics with platforming and puzzle-solving
Portal uses an engine that was meant for a first person shooter and creates puzzles that need solved through various stage with the use of platforming. While not the very first game to merge platforming with and FPS the puzzle aspects make it unique in that no other game had done this specific combination yet.
Pro Making it halfway and completing unlocks new content
Getting to the halfway point in Portal will unlock challenge maps and finishing the main story will unlock advanced chambers.
Pro The sequel contains an AI powered by a potato
If that is not funny, then nothing is.
Cons
Con Working with the level editor is difficult (no documentation)
There is not much documentation for the level editor in the game, as the creators primarily use it for themselves. There are of course many hotkeys you could accidentally press as well.
Con Obtuse puzzles, especially with optional content
Mediocre game design all around. Many puzzles are ordered badly or redundant and could have been combined or removed to smoothen the experience, as well as occasionally not exercising the bounds of certain elements (like ranged pickup). The game's optional content is even more worrisome as it often leads you to play hidden object games to look in hundreds of corners instead of using more difficult puzzles. One particularly egregious example is when you have to interpret a message in a very specific way after using a decryption algorithm you may not know about into another questionable input system.
Con Somewhat short
Portal takes 2-3 hours to complete which means it can be completed in one sitting. This may not be enough game for the money for some people and should be considered before purchasing.
Con Portal mechanics not used much to their best ability
Certain parts of the game sees the player using portals to manipulate sentry guns that fire rockets in order to progress in that stage, Mechanics like this make for a really enjoyable way to manipulate ones environment but sadly are not used too often.
Con Outdated graphics
The game was released in 2007, making it somewhat of an older title, because of this the graphics will not be on par with modern releases.
