I am an aggressive. I love adding to the flavor of a story and bringing in NPCs (I sometimes fall in love with NPCs and make them full characters). There are times when I want to be lazy though so I don't mind playing in a game someone else is directing.
Fantasy, be it full blown other world, modern Earth or spacey. I don't mind other genres. I love action in general.
Rope. Gives you the pleasure of watching them squirm while you choke the life out of them. Is easily destroyed, but can leave bruising or marks on your hands if done improperly. Then again...
Wrench/Pipe/Candlestick. Gives you the satisfaction of beating the bastard/cunt to death. Is hard to dispose of, but can be hidden in plain view. I'd rather use a baseball bat or chair leg. Burn it along with their body.
Knives are fun and just as intimate as the above two choices.
Gun. Severely overrated, boring, and overall unsatisfactory. Yawn e_e
