I bought the collector's edition guide AFTER I beat the game. I use it as a reference book because I'm constantly thinking about the Zelda games and the minor details all run together. I was watching Mases' video walkthrough as well and noticed that the very first puzzle of the Skyview Temple has multiple solutions. Mases suggests to hit the deku baba with a slingshot, run up the wall, kill the deku baba, then hit the switch. I hit the switch with the slingshot by angling around the deku baba. Other people's perspectives are always very interesting to me. I remember little things from way long ago like in my OOT guide, the writer wrote about how the Hover Boots suck because they make every place feel like the Ice Cavern. Stuff like that is very interesting.Yes, I agree the walkthroughs are fun after the fact because I always miss something and it is fun to find out what someone else discovered.
