Don't call any names. For me it's the guy who is always lagging behind me in progress (I've got platinum sword, he still hasn't even made wooden armor) because he just won't play the game. At night, he stays in a house so he doesn't have to fight the zombies. Nevermind getting coin and items off of them. But by the far the most annoying thing is he won't use any potions besides a healing potion because he thinks it's 'cheating'. "Spelunker potion shows you were all the treasure is, ironskin potion defeats the purpose of armor, etc" he says and then whines about me finding all the goodies.
