Which is worse: a game that is too easy or a game that is too hard?

I like a bit of a challenge but too hard is definitely worse than too easy. Your enjoyment of the game is greatly hindered by the constant frustration of being pummeled into the ground by the difficulty and when you are forced to repeat the same section of a game over and over until you can do it right, the case is usually that you see that part of the game so many times it begins to lose its appeal.

I found prince of persia VERY hard and Dragon Age VERY easy so i'm kinda confused by your examples but I hate hard games like some challenge but hard games just destroy fun.

At least i can beat it and see the full story then just stop and quit.

It really depends on what kind of challenge it is. An easy game could prove to have a great cathartic feel or could feel like a waste of time. While a hard game could be rewarding or simply frustrating. I'll go with inconsistent, as that is usually just annoying.

If the difficulty is very inconsistent throughout a game, it can really make the game worst than a game that is to easy and provides no sense of accomplishment or a game that is hard but can be extremely frustrating.

Very Hard cuz u might not get thru the game

I would say to hard, but I wouldn't call Dragon Age or Demon's Souls too hard.  I would consider too hard a game that is unfair, where the AI cheats to have an advantage or something.
 
too easy would be okay if the game still had a good story, or fun gameplay even if it was easy.

I clicked C, but really I guess it would be a game that's too hard because it causes frustration.
