Ranked in these QuestionsQuestion Ranking
Pros
Pro Rarely seen gameplay mechanic that combines multiple playthroughs
Each level is played through multiple times with every new playthrough adding previous playthroughs alongside current one. This is done 4 times trying to complete as much of the level as possible. It essentially creates a solo co-op experience and allows for lots of strategical planning forward.
Pro Vibrant aesthetic
The game has simple, clear, blocky levels and uses bright colors. There's an Iron Man inspired hud, but that can mostly be ignored unless you want to check out the score. Important information such as enemy count is displayed on the walls of levels and there's no need to keep track of health or ammo.
Pro Good weapon variety
The game has 6 different weapons that each has a progression system associated with 5 upgrade categories - Spread, Focus, Rapid, Punch and Acid. It adds another level of strategical depth as weapon upgrades have to be planned for.
Pro Level editor and Steam Workshop support
You can create your own levels to challenge yourself and your creativity. It feels really cool playing through levels you made, although you know what to expect.
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 Abandoned support
Currently the game does not work with the retail version of the Rift, a DK2 (beta Rift model) and older drivers will be necessary to play the game. There has been no word from the developer if this will be fixed.
Con Short
While there's definitely potential for multiple playthroughs to try and get a better score, the base game has just about 2 hours of gameplay.
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.
