I didn't want to spoil the voting since this is supposed to be title vs. title but not everyone plays by the rules, but it looks like its a runaway.
Obviously a monster like Tetris, virtually everyone has played it, and more than anything familiarity is king in the contests. If you've never played the Zelda game, Tetris wins by default. Venom had the one title that is arguably bigger than Tetris - Pac Man. Also, like Tetris, you can play Pac Man forever chasing a new high score. If you're stuck on an island with nothing else to do you may even figure out how to get past the kill screen.
