If you think you are creative enough, I challenge you to make an amazing fast action shooter where you don't HURT anyone; can you think outside the killbox to make something fun without blood and gore and hate? I bet you can't. If you can, you are a game design god.
P.S. Have fun, and please note that I fully respect and play bloody gory violent games all the time and will NOT look down on violent games, this is just a fun creative challenge. BLAST FREELY, gamedev friends! YOU choose what to do, there are no wrong answers.
