I don't use the walkthroughs in the first and second round, and I can either, I don't let myself do it, because why will you pay 50 dollars for something you're not really going to enjoy? Honestly, just passing a game without making any effort gives anyone some kind of joy? I can't comprehen those people.

But maybe on the Third round I use the walkthroughs so I can get everything I couldn't on the first to rounds. I've to say that I had use walkthroughs before ending a game the first time, but I just do that when I'm way too desperate. I just get desperate after spending 4 month trying to figure out how to advance.
