What Bool's Eye is suggesting is that you start with simple cd checks (in games which aren't encrypted) to get a feel for the task.
Then after you've done many, you will be able to adapt earlier versions' tuts to your newer game versions.

Cracking games can be very simple (Deus Ex, quake) to the extremely hard (sd2, latest securom) and require much asm knowledge. If you look for Krobar in google, you'll find lots of tuts for simpler tasks.

better to learn to crawl first, before attempting gymnastics.
