The original Pascal's Wager is a "proof" that following the Christian faith is a rational thing to do. It is a fundamentally flawed and reductionist approach to a major philosophical question, which tries to make an arithmetic problem out of concepts that do not translate well into quantitative terms. Put simply, it is: "If there's any chance at all that God is real, then worshipping him is the smart thing to do, since going to heaven is infinitely rewarding."
This is not an argument that should be taken very seriously. Even granting its conceptual framework, the god in question is hypothesized to be omniscient and not particularly well-disposed toward hypocrites. It's also questionable whether "infinity" is a valid term to use in an expected reward calculation, or that the probability of a god's existence can be meaningfully established.
Pascal's Wager, the game, presents itself as an extension and criticism of Pascal's Wager, the thought experiment; specifically, it challenges Pascal's implicit assertion that the Christian God's existence (P) or non-existence (not-P) together cover the full range of relevant possibilities. This is a pretty good concept, and a pretty good hook -- the premise creates (as Emily Short's review puts it) "an invitation to explore or express one's own personal morality through the player character, by choosing and acting out an alignment." However, this work makes no attempt to grapple with the deep metaphysical questions inherent in its premise and instead seems to target the very concepts of religion and morality themselves.
Pascal's Wager treats each of its six chosen religions equally negatively in that every one of them is conveyed as shallow and simplistic farce. Want to be a good little worshipper of Hanuman, the "Hindi god of strength and fitness?" (Spoiler - click to show)Disobey your parents and hit a baseball! Join a sports team instead of doing homework! Escape from prison on a rowboat to prove you are strong! How about a worshipper of Bacchus, the "Roman god of intoxication?" (Spoiler - click to show)Pop a Valium instead of caring for your infant sibling! Smoke a joint plucked from a urinal instead of doing homework! Inject yourself with an overdose of morphine instead of bothering to escape from prison! These are laughable misrepresentations of what are (or were) serious beliefs for many people, and the treatment of other religions is no better.
The ludicrous and over-the-top portrayal of these faiths may be intended to be humor. It does not strike me as funny. It seems mean-spirited ("mean" in the senses of both "cruel" and "petty") and anti-human. Perhaps the worst part is that its mockery is so lazy -- I learned more about several of the religions portrayed in a half-hour's reading on Wikipedia than the author seems to have ever researched in the course of writing this piece. (For example, in some traditions the infant Hanuman mistook the sun for a fruit and tried to eat it -- a metaphor that seems apt to mention in this context.)
Emily Short's very evenhanded review suggests that this game has only minor flaws. In my opinion, it has major flaws. It verges right on the cusp of 1-star territory for me, but I am forced to recognize that programming it was not a trivial effort, and -- again -- as a concept, the premise is solid. To the extent that I would recommend this game, it would be as a warning to would-be authors about the amount of work required to even begin to fulfill the expectations set by such an ambitious premise, and the disastrous outcome certain to result from massively underestimating the scale of one's chosen subject.
