Fair point. But ill still get the guide, which in the past has shown me everything that I wanted to do and see. I don't really recall that many errors. Sure there were a few, but none that seriously impacted the game. Im sure I mentioned earlier as well, it depends on your setup. For me I would have to walk across the room to my computer, then back again to my 360, trying to remember the information if its not something simple like a town name for example. Having the guide to hand is far more easier in my opinion.
Fortunately for me i have a laptop. A simple nice laptop i bought for 300 euro's 2 years ago. Best investment i have ever made.
Watching shows and reading comics while in bed, on the toilet or who knows where, is pretty cool.
And yes, that also means i can play my xbox360 with the laptop next to me. Reading forums, searching for cheats and hints has never been this easy. And not only for fallout 3, but hundreds of games.
If i had to buy guides for all those games, i would be in a huge debt haha.
Conclusion: dont buy expensive guides, buy a cheap laptop (or a mini laptop). Something that is actually worth the money.
