I recently finished Titan Quest (with the latest expansion), a Diablo clone. And I found that most of the gameplay wasn't just clicking: it was choosing on which enemy to click (to prioritise the most dangerous enemy first for example), when and where to use my skills/scrolls/potions; then outside of combat, which equipment to use, which skills/stats to upgrade, which upgrade to apply on which piece of equipment. Another important part was also the art style/ambience of the levels, which was an important part of my enjoyment of the game.

On the other hand I spent little time grinding and have little desire to play the game a second time on harder difficulty.
