Well do you.

I sometimes do.

At the moment I am on the last act on hardcore of gears 2 and I have availed of walk throughs to help me.

So how about you do you  or dont you?

I use them if I truly need them, but not much

only for dmc4, one part i was stuck

Only Achievement walkthroughs...

hidden goodies, nothing else.

I had to for metroid prime 2. Damn, that game was hard, especially those last 9 keys!

Everyone has to use them for collectibles in game. Like finding all the hidden packages in GTA, or most recently collecting all intel and destroying helgast symbols in killzone.

forget the walkthrough on gears, i'll help ya ;)

i may not have them acheievements, but its only laziness

i use walkthroughs to find collectibles only

Only if I really get stuck, which only happens in RPG's or Tomb raider usually

i don't use them that often, only when i get really stuck. i do use acheivement guides more often though.
