I don't see reasons to do it more than 2 times. The story being the same doesn't make me want to do it all over again. The game is great, the best I've played so far. But I prefer to wait for future updates, if any.
The David The Developer is working on his next game.
Exiled Kingdoms was always planned to have an end to development.
You can try playing the game as a different class, different difficulty setting, or with different role play considerations.
