edit: maybe Light vs Darkness is better than good versus evil. Think of
Archon!
Okay I am thinking about organizing a Good (or Neutral) magic versus Evil magic game in the near future. The basic idea is that Team Evil Magic will be comprised of Blood, Death and maybe some of the nastier Astral spells, or maybe just Astral. Team Good (or Neutral) Magic will be comprised of Fire, Air, Water, Earth and Nature.
So the basic idea is that the Dark pretender gods of the world have been practicing magic which has threatens to the magical landscape/fabric of space-time/magical aether/etc. and threatens to destroy all the other gods. The result is strange events are becoming more and more common, and horrors are starting to appear and randomly attack people. So this of course gives all the other gods a reason to band together and stop them. Also each side will have magic and strategies that is unique to their side, which should be interesting.
There are a number of ways to go with this. The simplest way is to have Team Darkness and Team Light fight it out until only one team is left standing. Or there could also be a time limit of some sort. For instance if Team Darkness succeeds in casting a certain spell or combination of spells (say, Utterdark, Astral Corruption, and Burden of Time), Team Darkness automatically wins. Another option is requiring Team Darkness to capture certain magical nodes or artifacts of great power in order to win (ie Victory Points). Or something else similar that gives each team a sense of mission and urgency so it's not just about counting units and resources.
Another cool thing is that skill level shouldn't be as big a deal since we can just balance things out by having some newbies and some experienced players on each team. Anyway that's the basic idea. In general, I want to keep the rules simple, but I want to give the game enough structure so that it feels thematically interesting while being challenging and fun for both sides. Anyway, all constructive input and suggestions are welcome.
