and to double your calories, which is like XP for the human body.
NOTE: Ignore cheap knock-off bags of Nacho Cornitos and bottles of Mountain Lightning offering Triple XP, as they are only able to be redeemed for Mike Piazza's Strike Zone (N64).
because there would be no point in getting the game if you didn't also get some crappy skin you'll probably never use. Also, yeah, you definitely need to reserve a copy of this game, it's not like there are going to be tons and tons of copies leftover all over town.
so you'll know exactly what to do to increase your Gamerscore instead of just playing to have fun.
NOTE: Gamerscore is the most important score in your life, right behind credit score, SAT score, and daily caloric intake from Doritos.
Don't forget it's Election Day! Get out there and do your civic duty, since it's entirely possible someone left some discarded Doritos bag or Mountain Dew bottle in the voting booth.
