Most of the game-world takes place above ground, so if you were hoping for huge, complex, multi-level dungeons, you're going to be in for a real disappointment. The monsters also regenerate constantly, which can be a huge issue when you can't stock up on enough potions to reach an area far away. You'll go a little ways, find you're running out of healing potions before you ever reach the goal, return to the town to grab the small available stock of those potions, and then try yet again to reach your goal, only to find almost as many monsters in your way as before. It would have been nice if the merchants had infinite potions or eased off of the regenerating monsters. By doing neither, Sacred just becomes unnecessarily difficult, and not in a fun way. You'll probably find yourself running or riding past hordes of monsters in the hopes of saving your potions for the later, quest-related battles.
