Ahhh, all this reminds me of my good old days playing Arcanum (i.e., yesterday). It had a satisfying set of consequences for all of your actions - not to mention the reputation system (Pervert of Tarant springs to mind...). Would you, in the end, side with Kerghan, ultimately becoming the last living being in Arcanum? Or would you kill him, and preserve the balance? What happened to Tarant? The Black Mountain Mines? Vendigroth? It also had a nice alternate storyline, which could result in a few towns slapping the kill-on-sight order on you - and resulted in you slaughtering Stillwater to further the storyline.
