I only used a guide for Giruvegan as well. That place without a map gives me gangrene. I rarely use guides with games because it annoys me to stop playing, read, start playing, stop playing, read, etc. I dunno, something about it all just drives me nuts.
I just want to sit back, smoke a politically incorrect candy-cigarette they used to sell when I was still a youngin', and play without the fuss.
