Using a strategy guide: Does it ruin the game experience?

[Joemanji]

I check it out too if I'm stuck and absolutely have no idea where to look next. But other than that I'll go check it out after I finished the game. Just to look for the last hidden stuff in the game. To see if I didn't miss something you know. Strategy guides can spoil a game though. Especially boss battles and other storyline spoilers. Strategy guides for RPG's is the worst kind. It spoils alot of the experience. The whole reason puzzle solving is great is because you solve it yourself.

Edit: Use the guide as a tool like u can use a dictionary for puzzles. But don't base your game around the guide. That's no fun.
