Mage Hack is an urban fantasy game that has some really interesting looking mechanics and ideas. Playing on the idea of a flexible magic system in which you can do pretty much anything and running with it. 

The rules seem pretty good and are very light overall. Character creation is fast and easy with most emphasis focused on the characters magic. 

The majority of the rules focus on magic. For the magic rules I love the philosophy system which allows for the creation of any kind of magic user. Be they wizards in a tower, mad scientists, or secretive witches. The magic relies on a charge system where you roll to collect charges for your spells. The magic is flexible and diverse relying on creating spells in six magical schools which align with each of your stats. Where as far as I read your character could do anything if they had enough time and reached a high enough level. 

Overall I like the magic system. It's flexible giving your characters the ability to cast whatever spells they want and while somewhat complicated is fairly easy to manage once you get the hang of it. 

I do dislike that character creation requires rolling for stats and no alternatives to doing so are provided. But I understand that this is based on the black hack which is in tern based on 1970s role-playing games so I suppose that it's expected. 

The game is generic and has little in the way of setting. Though it does have some rules on other worlds and possible antagonists such as an invasion of fairies or aliens. It can be used for pretty much any urban fantasy setting so long as your ok with extremely freeform magic. It does however seem at times that the game was designed to be "mage the ascension, with better rules" especially considering the philosophy examples seem to be the 9 traditions with the serial numbers filed off. I do feel like a good setting could be made from this though and overall I think it's a good system to work with if you like flexible urban magic.
