I accept your challenge!
Still, difficulty sliders could be very interesting. Especially if there were more than one way to increase or decrease difficulty. Like for exp: Easy (old algorithm), medium (current algorithm), hard (current algorithm, +1 exp per level to level), extreme (bonus exp -2, +1 exp per level to level), AVATAR (no bonus exp).
We made an expansion and it is awesome. Really, you should check it out, especially if you're looking for some extra challenge.
