Do you know another series that combined sci-fi and action rpg gaming? /honest question ^^

And about the dying characters, i haven't even managed to get anyone killed so far, no matter my choices. I take it Tali dies if you 1) present the evidence and 2) get her exiled but you'd have to make some pretty wishy-washy choices for that to happen because even exile does not lead directly to no loyalty and if she's not loyal, don't put her in the vent (except take her with your squad). There are only very few characters and choices where doing the loyalty mission does not give the loyal status, which is as i understand it the only way for anyone to die in the "suicide" mission, as Long as Garrus leads the strike teams and the "hold the line" squad and in that squad is at least Zaeed, Grunt, Miranda and Jacob you can't even lose the game. (as in, die)
