"You have one set of upgrades for holy experience and one for unholy. "Ah ha ha ha ha ha!" you might say. "Moral choice system, hmmm?" "Well, not really," I would reply. "More a violent option or equally violent but better spirited option." "And I suppose," you would continue, "that since holy points are slightly harder to get that holy upgrades would be slightly better, and that it all might be leading toward some alternative ending scenario where too many damnations land you a big, fat, steaming two-bedroom apartment made of poo and sawblades on the Ninth Circle?" "No," say I. "I presume that was the original intention, but I guess they used up the ending cinematic budget rendering Dante's hairy bum (spoiler alert) and the upgrade tracks are pretty much equivocal." "So what's the point of having two separate experience levels?" you ask. "Well, it's like my right hand on a Sunday night," I say. "Why is that?" you ask. "It beats the fuck out of me!""
