In Diablo you click, click, click (to destroy enemies) and then they drop loot, you collect it and click, click, click, collect loot, click, click.. later you use the loot for some crafting.
In Minecraft you click, click, click to destroy world blocks. You collect loot (resources) and you do some crafting after it. Besides that you have some enemies to defeat. Terraria works the same way.
A space simulator also works that way, you can kill enemies, collect loot and improve your ship later on. In games like X3 you can even build space stations, factories, new ships and much more.
Man, you're right! Take, say, Tetris. You're just clicking buttons, right? Click, click, click. To make a line. The same game!
Or racing games! You just click buttons (some longer than others). Click, click. And then, you win the race, but it's still just hitting buttons.
Or strategy games. Or RPGs. Or any game ever conceived.
This point is often brought up, but I don't think there's much to it. What this does is deconstructing the INTERFACE. But that's not what games are about. Games are about decisions, and those are fundamentally different in Diablo or Minecraft, or Racing games, or whatever.
