I wish I could be one of those who are only caught up on maxing my rank!! To me though, you have not "completed/beat" a game until you have earned EVERY rank, armor piece,achievement,COMMENDATION,level, etc... Only then should you consider yourself a "diehard". OFC Halo 12 will probably be out by the time that happens but still.. I would like to ad 100% completion of ALL Halo games to my "bucket list"...
Peace & Happy Gaming!
