HoMM is an RPG?
It's been seven years. Do we have an answer yet?
edit: rofl
"No betrayal" meant that key NPCs couldn't turn on the player, lie to the player if they were honest in the past, nor could an NPC steal an item from the player, etc. This is good as a general rule, but it's the kind of rule that begs for exceptions.
Why make a rule like that? It makes no sense at all, in fact it's quite stupid. I hope he who made that rule won't be involved in the design of fallout 3.
