Selective Resurrection
Almost all RPGs contain a spell or set of spells for bringing dead characters back to life. Almost all said RPGs also contain at least one story scene where a character is killed, because the hacks who write video game scripts just can’t get enough pathos. It is never possible to bring a character who dies in a story scene back to life using the resurrection spells; sometimes games will try to explain this phenomenon (usually with stupid results), but usually it’s just taken for granted that somebody who dies in a cutscene is dead forever.
