Well, maybe descend isn’t quite the right word. It’s more like they were peacefully standing outside the convention center waving signs with slogans like “EA = Electronic Anti-Christ,” and “Hell Is Not A Game.” Although, for the record, Hell totally is a game; it came out on the 3DO, no less.
So what is it about Dante’s Inferno that got these protestors, The Saved Group, so riled up? According to member Cherry Adams, it’s because they feel it “disrespects [themselves], the Bible, [and] the Christian belief.” Specifically, they don’t like that Dante can leave Hell, his usage of a crucifix as a weapon, and all the violence in general. She affirms that “we don't need this right now in our society.”
[Update: Some matlocking in the comments shows that this may actually just be a PR stunt. Props to EA, if so.]
