I bet only a handful of us posters are able to write details guides like he did. I know I can't and I'm sure most can't. Just have a look at his guides on GameFAQs. Listen to his podcasts, especially the ones about the best games on PS for example. I would say he knows gaming about as much as us enthusiasts do.
I would say that he knows about gaming no more than most enthisiasts do. That's my point.
I do listen to his podcasts, and I'm familiar with guides in general. Once you understand the structure, it's just about filling them in with the details. Again, if you have a favorite game that you've played multiple times, you probably know it well enough to make a guide. And if there are small details you don't know off of memory, you probably know the game well enough to figure out how to find them. That's essentially how guides are made. Anyone can do it. You just need to be good at the game and have the patient to put in the work. That doesn't take an exceptional amount of knowledge about games in general. At least not more than your average game enthusiast. It's not difficult - it's boring and tedious, like transcribing spoken word to at a court or something. Everything is there for you. You just have to be willing to do it.
Well, this is new.
