One of the most satisfying moments in the game is when you finally take down a tough boss after trying for ages. The sense of accomplishment is amazing, and the loot you get is always worth it. And then there are the weird surprises - like when you stumble upon a hidden dungeon or a secret area that's filled with crazy-hard enemies.

The challenges in the game are really cool too - they're all about testing your skills and pushing you to be better. You'll have to use all your wits and reflexes to overcome them, and the sense of pride you get when you succeed is awesome. And let's not forget the little details - like the way the environment changes as you progress through the game, or the way the soundtrack adapts to the action on screen.
