See, what I'm seeing in this here thread is a certain amount of overestimation of the concept of a "mechanic" in a game.
A "mechanic" is a very simple game rule that governs an aspect of the game world and the player's interaction with it.
Let's look at a game which truly has a small number of mechanics, Bejewelled.
There are actually three mechanics in Bejewelled. The first is the player's interaction, the player can swap the position of any two gems horizontally or vertically.
The second is that if three or more gems are together in a horizontal or vertical line, they disappear.
The third is that new gems fall from the top of the screen to replace any gems which disappear in this fashion.
Changing any one of those three would significantly change the nature of the player's interaction. If you could perform diagonal swaps, for instance, there would be many many more opportunities to make lines. Likewise if you could make diagonal lines. If gems fell in different directions (Say, always along the line you created, as will be the case in the new Puzzle Quest game), the player's ability to create chains of matches (note: That isn't a mechanic, it's an emergent result of mechanics two and three) would be vastly altered.
Bejewelled is a very simple game mechanically, but becomes quite deep as you plan two, three, or even more moves ahead, anticipating the results of the various mechanics interacting.
None of the proposals so far have anything like two mechanics. Most would require a great many more. (the only explicitly defined mechanic yet is the OP's Dragons's Lair extended QTE, which literally is only one mechanic for a game, press the right input at the right time to continue watching a predetermined event unfold). The other "Section" requires a very great number of mechanics, as a driving game requires mechanics for steering, acceleration, and crashing at the very least, and most of those will be subdivided into different individual mechanics, even when they are emergent from a physics based engine like most modern driving games.
