Two nations go to war. One is a theocracy whose army sports fighters, paladins and clerics. The second is a magocracy, whose army consists of fighters and wizards. Their numbers are equal.
The Thieves Guild. Both the magocracy and theocracy kick each others asses, decimating both countries. The thieves guild in both form an alliance and take over the two countries.
This isn't about who the DM wants to win. Its just a thought that crept into my head and I thought it interesting. So assume no bias or no extra favors on the "good guys."
Well, if d20 is so balanced like it's supposed to be, then everyone dies.
But we all know that isn't true. Theology buffs up the fighters and paladins and they decimate the Magocracy's fighter. But the Magocracy themselves have the better combat spells and destroy the paladins and fighters. With most or all the spells used up the Theocracy wins cause they actually have fighting skills.
