Well, first of all, my lovely friend at EB decided to throw in the Strategy Guide for free with the game. So I will be getting one. However, I will play a fair bit of the game before opening it.
Secondly, I won't be looking at the Missions until I complete the Main-Story Missions.
I don't like the Strategy Guide for the Mission Help anyway, I like it to read a well-organised bunch of Information on the cars, people, etc, of San Andreas. It's like an assembly of all the features that adds more pieces to the story. It's just something good to read, when you can't be bothered going on the Internet for the 100th time today. If you get what I mean. It's also much better organised.
I'm sure this is what Blake would have liked to said, but couldn't be bothered wording it like this.
It's not for help with the game, it's just reading material. And if you don't like it, then that's your choice Mr. Murphy.
