[color:"orange"]Where can someone create a game that you want to play over and over?[/color]
I don't want to play a game over and over, any more than I would read the same book or watch the same movie repeatedly. Depending on the depth of story, etc I might play a game a couple or few times, though usually with a break inbetween. I just finished PS:T for the first time a little while ago, and could probably go through it again now if I didn't have half a dozen other unplayed games collecting dust on a shelf.
Games that can be played over and over are monotonous. I never finished Diablo or Diablo II, because of that. The multi-player aspect was fun, when my schedule matched up with my brother's. There was some challenge / fun in character building and equipment finding, but ultimately it was all rather pointless and repetitive hack-and-slash, IMNSHO.

You say that like it's a bad thing.
At least with a story there is some depth to the game and characters can have backgrounds and motivation for their actions. If the story is detailed or interesting enough, you can play through it multiple times. Without a story, you're left with just some brief premise (at best) to loosely tie together a bunch of hunt and fetch quests. In this case, the only reason to play is basically to assemble a set of skills and equipment to most effectively kill monsters. This can also be done if the game has a story, though generally not to the same extent.
Unfortunately, too many people seem to be content with just character building (though without much actual character). Personally, I'd prefer more support and demand for story driven RPGs than action RPGs, especially since the RPG category is a small segment of the gaming market to begin with.
