Completely different platform, but Izuna's interesting looking to me. Otherwise I really can't contribute much to this topic. :P
Yeah, my roommate bought Izuna and I've been doing some reading about it. I like the fact that it's apparently hard as hell and they permanently delete your equipment every time you die. But the game play looks pretty boring and overly simple. Gamespot described the difficulty as "barbaric" which sounds pretty badass to me. I'll give it a whirl one of these days.
