The original fighting game (by Technos Japan!), and inspired the next step, Yie Ar KUNG-FU (see entry 1379). Champ was a dual-stick game when it came out in the arcades in '84, and uses dual analog control on the PS4: each attack (or dodge?) is executed via a particular combination of two cardinal directions input simultaneously, one from each stick. It's rather confusing and I didn't come close to getting the hang of it on my first outing--but then, rounds are over in a single hit, so there isn't much time to get used to things.
Kind of fascinating but so far not all that fun to play.
