While making your weapons, don't make all swords or something like that, make a varity of kinds. Make bows, magic, swords, staff, and other things, this way any one who plays ur game will be satisfiyed. Also, don't make 6-9 weapons that are awsome, make your 9th weapon pretty strong. Then, maker your 11th a little stronger, ect., ect., ect.
