The thing why you probably don't like the first dungeon is that you have to do it first (except for a few short quests), this is in a lot of rpg's. First there is a dungeon or something which you have to start with and when you have done that, the whole world comes open so then you can choose to go to this town or that town or do that quest and such. But in the start of the game you have to do that one dungeon.

So if you play the rpg out for a 5 times you first have to finish the dungeon, where you know every secret, and where you know where all the monsters stand and such.
