Sure, call me the Runescape ***, but it'd be very cool to see what happens when you mix Graal and Runescape together. Equipping various armor and weapons such as a Dragon Full Helmet and a Penace Torso, training various skills such as Crafting, Fishing, and Mining, and completing various tasks around the world like "Vampire Slayer" or "Hero's Quest".
This would give new features Graal has never seen before like random events. The only thing that could possibly be flawed is the Grand Exchange due to lack of players, but we have shops for that.
