We like being challenged by games, but sometimes if we're stuck in a particular spot for too long, we can get really frustrated. Then we have the inevitable, "Should I check a walkthrough?" debate, although our weak-willed selves will try to resist as long as possible.
What do you think about walkthroughs, though, and how often do you use them? Only when you're really stuck? Always, to make sure you get every item possible? Or, maybe even never, no matter how long you've been unable to progress?
