Oh goody, Dimitri has a 'brother' now, and bonus, they've got the perfect little yin-yang thing going with their personalities :P.

And I'm inclined to agree with Soul though guys, I know I may have said no one ever wants to be the villain, but what I was trying to imply is that the scale is almost always massively tipped towards the protagonists, not that every one needed an evil CS. What i've learned is that when and RP like this is presented, people always want to be the heroes/radicals/rebels instead of the villains/government/militia, and that usually makes things harder on the GM seeing as now it is solely on them to find someway to keep everyone engaged, come up with the plot, manage their own specific character, and keep the Rp from getting stale/stagnant because NPC villains are usually cannon fodder. If a few people actively RPs as villains it gives the GM a chance to work out a plot AND allows the heroes a worthy challenge seeing as they now have an enemy that won't just be taken down in one post. However, much like the hero thing, too many villains generate stagnation, albeit with more violence seeing as these are villains.

tl;dr - Balance between the number of heroes and villains is key.
