I'm of the opinion that this thing is getting out of hand though. There really isn't a need for everyone to jump into a great war over what was in effect a minor raid
There was really no reason for europe to plunge into a massive war over what was in effect a minor assassination. But it happened, simply because everyone had a itchy trigger finger. And lots of guns.
The short answer there was that a Victorian alliance system of nations had moved into the age of warfare on an industrial scale without realizing. WWI happened at the end of one era and the begining of another. Basicly what is happening in the godhood game (as ragnarok says) is the pack singling out the one who appears the strongist and eliminating him as a threat. It's a very common phenominon in PBEM's (and forum games too). Everyone wants to "win" and if somebody looks like their in a good chance they find the other players turning on them. The next stage of proceedings is that when the pack starts to look too strong then others ally with the victim or the pack splits and starts fighting in different camps. It's why I always choose goals in internet games that don't revolve around "winning" but instead try to acheve certain things. For me the story is more important than who wins or loses.
What you really should be wary of is setting a precedence. If the Magus turns on the other gods when he thnks they grow too powerful then should he find himself in that position then others won't hesitate to do the same to him. It's easy to get lost in the petty powerplays of the players and lose sight of the game itself when these things happen.
don't get me wrong I'm excited about the first conflict of gods, just lets not let it degenerate into perpetual warfare. I can understand certain gods maintaining a continuous state of war (Aarseral and The Wander for instance) but I'd hate to see two monolithic alliance systems forcing everyone to choose sides. This was afteralll how WWI began. Remember alliances are as much a burden as they are a blessing.
