Pros
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.
