Nooooo Don't play the Miles Edgeworth first D: You gotta go in order, or you won't understand some stuff... Or perhaps the Miles Edgeworth's games have a different story. I dunno Hannah.
I only played the Phoenix Wright and Apollo Justice ones. So yea. OOOH AND I've heard that the ME games are the hardest! Good luck, have fun! ^_^
