Everything that has a listing of some sort of ranking by default is indirectly or directly a competition, maybe not to #15 or #2, maybe it is to #4 or #20 .. It's just game-play and perhaps not taken too serious, but it's still a fun little competition. Regular and active players stick together as well. Seeing how you're progressing through listings and rankings is what adds an extra layer of gameplay to the game. Pretending to ignore it is like having breakfast without bacon; you know you're missing something.
