My personal favourites from that year are Bard's Tale and Ultima IV - but that's in retrospect.
Games I actually played the most from '85 are Ghost'n'Goblins, Gauntlet, The Way of the Exploding Fist, Commando and Daley Thompson's Decathlon.
I honestly never cared much for SMB, scrolling platforming never really appealed to me, as opposed to exploration based platforming of games from that era.
I voted for Tetris, though I was also never really much into it.
