In HL2 the tutorials are really great. First, there are a lot of mini-tutorials throughout the game with no instructions where you can not advance until you learn some easy skill - like breaking wood with crowbar, shooting a padlock to open a door, putting concrete blocks on a swing for it to rise, etc. Then, there are cases where you'd want to practice a skill before the using it in battle - like using Magnusson devices to hit striders. You get instructions and a chance to fire it seveal times to get a feeling of its trajectory without having to load the game a dozen times during the real battle.
