The three things that annoy me the most are;
1. "Wall of death", for example see James Bond for Wii. This is a FPS exclusive, where as soon as you crouch out of cover you are immediatly shoot fifty times and instantly die. It does not matter if you sneak around and stick your head up from another cover, because the enemy magically always know exactly where you are, reacts with superhuman speed and have perfect aim.

2. "Extreme leveling", for example see any unbalanced J-RPG or RPG, such as FF or NWN. What it means is that if you have the right level or above, all fights are a boring cakewalk grinding. If you have to few levels, all fights are impossible. Like, you use all the fucking potions and wands and whatnots and still get brutalized no matter what. Within limits, of course - nobody expects the final boss to be beatable at level 1, and that Fathamurk requires level 13 (although I did it on level

3. "Hidden switch", for example see the Marathon series. What this means is that there is a puzzle crucial to finish the game which is perhaps not as much difficult as much as "for fuck sake I did not think of that". For example, I was playing "The Dig" for Macintosh, and since Mac do not have a right button, you use apple-click instead. Well, nothing in the game requires "right button" EXCEPT some fucking tortoise skeleton you are supposed to put together, and you try in all possible different comibations only to later find out that you can rotate the bones with apple-clicking

Does anything of this apply to Eschalon III?
