The Achievement system is a step in the right direction. Pet and RPG systems would just add more clutter. I think, to improve Unholy Nation, you need to really think of a way you can move forward, instead of to the sides. Choose a basis or an idea you can keep going with for years. Basing your future releases around the core of the server would be a good start, which I see as PKing and Events because to be honest with you guys, that's all you really have going for you at the moment in terms of gripping features.
