I miss things from UO(Ultima Online) like being able 2 kill anyone anywhere(yes no safe zones), and being able 2 loot all the things that the person had on their character before death.
I miss the ability 2 cut someones corpse into pieces and take someones head and store it in the chest inside of your castle, or impaling it on the fence of your castle, I miss having a room full of players limbs. Also it was fun 2 have your own castle, tower, house, whatever and the option of placing it where you wanted. I miss mounts, I miss taming monsters, having a couple of tamed dragons… I miss the option of crafting nearly anything and placing it wherever you wanted. Those moments when you reached a top of some mountain and there was a random carpet on the ground, and you ask yourself why the hell did someone leave a carpet here…
