Role Playing Games are problematic by nature. From my experience, with both PnP and CRPGs, the player wants the skill and abilities of his character while ignoring the limitations. In PnP you get players arguing with the DM, what can be done in one action, what your character "should" be able to do, the moral hazard of player knowledge vs. character knowledge, etc. If a CRPG is first person, you think, I can put my reticule on that enemy's head, he is asleep, why can't I one shot him? RPGs place a numerical abstraction layer between the player and the game world, fundamentally breaking the immersion offered by first person perspective. In isometric, you can see behind walls, things your character shouldn't rightly know about. There has never been a perfect RPG; Role Playing Games are problematic by nature.
