The big questions in trying to do Amber as an rpg.
Can you emulate the dramatic conflicts of the novels?
Will your game’s attribute conflicts reinforce the canon?
Will your conflicts follow what Zelazny says is important in this universe?
Can you defend secrets that might save Amber? Or destroy it?
Benedict, Oberon, Llewella
Can you discover who your enemy really is?
Caine, Julian, Fiona
Can shadow reveal a resource that will throw the battle in your favor despite your opponent’s resources?
Corwin, Rinaldo, Bleys
Can you bind things to your legend that intimidate your sibs?
Julian, Delwin, Merlin
Can you control the weather with only a few scratchy notes for inspiration?
Eric, Corwin, Random
Can you work up enough prestige to take a throne? To be admired?
Eric, Merlin, Gerard
Can you build Merlin or Rinaldo or Martin (and not need more ‘attribute resources’ than other family ten times your age?)
Can you build a Random able to beat Eric at cards but lose to him with the blade?
Does your system of attributes work in Zelazny’s Chaos?
Does it work for shadow sorcerers?
Does it support Mask? Jasra? Melman?
Can you introduce strange new powers without breaking the canon set?
Is it fun?
Will it ‘tailor awesomeness’ for the PCs?
These are reasons to examine the existing system and change it.
