Pros
Pro Innovative, parkour-inspired, first-person platforming with excellent sense of motion
The game's core mechanic is about traversing levels using wall-jumps, rolls and slides without losing momentum. It does a great job of creating a fluid sense of motion that you have complete control over.
Pro Time trials
There are time trial bonus levels that are free of platforming sections and combat, just pure timed running missions.
Pro Unique, minimalistic art-style
Mirror's Edge is set in a world where a totalitarian government runs a city and tries to eliminate anything that stands out, such as the free-running protagonist. The levels are created minimalistic, mostly white with aggressively contrasting primary colors, to represent the oppressive nature and sterility of the world.
Pro Great soundtrack
The soundtrack's spacious ambient texture coupled with electronic beats and synthetic sounds supplement the game's otherworldly, contrasting setting. The complete soundtrack is available with the purchase of the game.
Pro Keyboard controls work quite well
Surprisingly (for an EA game especially) the keyboard controls are actually designed to work quite well.
Pro Non-PvP servers are available
If worrying that another player might kill you and loot your corpse is not your thing, or if you don't want to deal with someone constantly harassing your base, there are servers available that take away the risk of other player's malicious behavior.
Pro Building system is simple, efficient and intuitive
Hold a key while holding a hammer, and with your cursor, select the piece you want to build.
Upgrading a piece of building is done in the same fashion.
Pro Game's multiplayer nature creates psychological tension
While there's obviously potential for working together with other players towards achieving certain goals, the more likely scenario is someone trying to kill you to get your stuff. Or even worse, deceiving you in working together to achieve a particularly difficult goal only to stab you in the back when you're not needed anymore. It's easier to take stuff from someone else than gather it yourself. And since your base is a the perfect bullseye to other players, there is constant threat of griefing.
Pro Lots of variety in ways to die
Fauna, including bears and wolves, is trying to kill you, radiation, that's ever-present, is trying to kill you, zombies, in a multitude of colors, are trying to kill you, other players on the server, equipped with guns, are most definitely trying to kill you, and you, yourself, if you don't find food, will die.
Pro Base building allows for less punishing gameplay
Because you can build your base that you respawn back to when killed, losing only what you had on you at the time of death, it allows getting back to where you left off quickly.
Cons
Con Poor combat sytem
The combat system often feels out of place and definitely interferes with the flow of the gameplay.
Con Some people may experience motion sickness
In order to maintain its immersive nature, Mirrors Edge has virtually no UI, other than a small dot at the center of the screen. This should ward off motion sickness for most people, but be aware that if you're queasy, you might not feel too well after playing.
Con Hard to play solo
Rust is all about clans fighting for territory and loots. Solo players (or ones with a couple friends) can easily be killed by bigger clans.
Con Not yet finished (buggy)
Since it's a Steam Early Access game it still has lots of glitches, placeholder text and unreliable infrastructure. But for all its unfinished nature, it's surprisingly playable.
