I want to start out by saying that this is not originally my idea- it came from someone else's mind, but it appears to have died, so I wanted to try and revive something similar.
I would like to do an EDH-ish RP: multi-person format, with each one a different commander, the battles all about diplomacy and intrigue and backstabbing and the like: no rules other than we, as the writers, should be having some fun with it. Paragraph format IS preferred, and I would hope any who want to participate put some effort and pride behind what they're writing.
If you want more details, I have a more specific scenario in mind, but before I start going that far into specifics: Is anyone interested?
Alright. The idea here is it's going to be centered on a basic idea of good versus evil on a plain as yet unrevealed in MTG lore. The plain is fairly basic, with a civilization of humans that has only barely begun working into technology, with planeswalkers coming and going, their coming being seen as the descent of a god to the earthly realm, their going being viewed as the plain and their peoples being deemed unworthy. The 'commanders' have been dragged here by a small clan of five walkers who summon them to begin restructuring the world, to help these humans survive a new threat: a 'walker by the name of Fyna has been summoning her own brood of slivers to this plain, and the commanders have been brought forth to gather the armies, to rally the humans of the plane, and to stop the other.... Or, to help her, depending on their allegiance.
The idea here is, once again, diplomacy, so the commanders have all the choice they want to let the world burn, or to help burn it, or to stop the armageddon of slivers. And what they choose to do will decide the fate of the plane.
For reasons that are divided amongst the walkers: A, because this way is more fun, and for the more morally inclined walkers, B, because they're busy helping other planes with similar problems.
Most of them wouldn't, on arrival. But the moral walkers, the ones who think themselves good guys, should be swayed by the keenings of the dying and those related to the dead.
In my experience trust and discussion are the greatest things for this sort of RP: combat RP will generally be trust-based, each player controlling only their own characters' actions, and making sure all sides consider the actions fair. Non-combat RP will be more generally less restricted, again each person allowed their agency and what-not to run their characters as they see fit, with my only role being to showcase the reactions of the people and the plane and the Enemy, acting as a DM: I'm there to run the world, and the characters can do what they wish therein.
Existing 'walkers will make a cameo, but will not be key characters
Either or, but with an expressed preference for the former: it makes characters more defined and obvious, as far as I'm concerned.
Either or, at the writer's discretion. I would like say common sense, as far as that goes: again, the watchword is cooperation, each person allowed to make their decisions within reason, as long as everyone considers their choices 'fair'. With how varied and different characters in magic are, no one rule really fits all of them. But if people don't like the idea of that I'm willing, and fine with, using pre established rules from one WP or another. I would just prefer a bit more freedom than that.
