I just couldn't get into this game. The story telling was not compelling. When some random stranger guy came up to me and wanted me to nuke the first town, I was like "Why isn't there an option to turn the dude in and let them hang him? Why would this guy come up to a stranger asking him to set off a nuke?"
You can turn him in. And he asks you to blow up the town because you're an outsider and I'm pretty sure you had to indicate that you're not burdened by a highly moral character, either. Plus he's extremely cocky and arrogant, and doesn't feel that the plebs would be much of a match for him even if you told someone.
