-Engaging story: Though not so much important to me with arcade style games. The story has to make me care about the outcome or the protagonist for me to really enjoy it.
-Characters aren't annoying and if they are I can make them die horrible deaths if I want to
-Replayability: I usually keep my games so I'd like to still have fun going back to it every now and again
-Amazing music: If I am going to spend hours on something with looped music it better be good.
