Raziel or Kain? Both of them are cool characters.
But if they're making a new game for Kain, they should remove that silly "you fall into water, you die" crap. That annoyed the hell out of me in Defiance. I mean, shouldn't like, an all-powerful vampire lord be a little less hydrophobic? I'd figure it would make sense if being in water slowly drains your health, but instant death? WHY?
Also, I hope the game would have lots of "Vae Victis!"
