I will pass on the amber game i think... if i really want to play it i can just take the spanner to Nobilis and change that. It's diceless, but has a very different system.
4 stats.
Aspect - everything physical and mental that a human can, or could, do.
Domain - the idea the PC has contol over. The PC is elemental, lord, guardian and master of this idea. IT can be anything, from love, hate, blood, cats, the english language... anything.
Realm - the amount of control over the PC's homebase the character has (since the characters are always at war in a nobilis game, this is more important than you would think)
Spirit - The PC's ability to defend againsts miracle, and other stuff like flower rites and binding humans.
Each of these ratings can be bought up from level 0 up to level 5. You also get a pool of miracle points - think like willpower from white wolf game. Each attribute has its own pool.
In game, there are 9 levels of miracles for each attribute. If your rating in that attribute is equal to or greater, you do it automatically. If your rating is lower, you have to increase it with your miracle points. these only regain at the start of a story.
Example. Say you have aspect level 4. Somebody shoots a uzi at you. Checking the table, you see that parrying an uzi's spray of bullets is level 6 aspect (impossible for normal human). You need to spend 2 miracle points to do so.
There are also gifts, like flight, immortality, turn to stone (like medusa), shapechange. There are guidelines for making your own gifts, using the rules for domain. Interestingly, the flaws do not give character creation points. Instead they give you miracle points in a pool of your choosing. The flaws are divided into two sections : general ones that apply all the time (blindness) and those that only cause a problem at specific times (cannot enter a house without permission). The general ones give miracle points at the start of each story, the specific ones only when they become a problem.
From what i have seen on the Nobilis mailing list, there seems to be a migration of amber players to Nobilis.
Im currently thinking of using Nobilis for the matrix...
