Yes I do, but usually only for myself, and for the fun of it.

I can't remember the tuts I looked at years ago, as I started reverse engineering old win progs before I turned to games. But the Krobar site is one of the best for all sorts of cracking apps tuts.

the other two sites are good, I've heard, as well.

If it's something you're interested in, then I'd start reversing simple cd checks first (only using any tuts as a "i'm stuck" guide to begin with)

Deus Ex is a good example of a "window box type cd check", and a good place to start.
