Some people climb mountains, because they're there. Others try to eat the most hotdogs in one sitting (because their bodies enjoy a surge of high cholesterol in a short amount of time or the feeling of throwing up afterwards?). We're all inspired to do something, even if that something is playing through a video game without taking damage, or receiving that 1-point Achievement for 50 hours of gameplay. Whatever floats your boat, gamers, we salute you! Here are some of the toughest (and stupidest?) Xbox 360 Achievements. Final Fantasy XI - "Reach Level 75 [with any of the 20 character classes]" (30G) It reportedly takes at least 100 (perhaps even hundreds) of hours to reach level 75 with a character in Final Fantasy XI. If you can do it you'll be awarded with an additional 30 gamerscore. Now try it again--19 more times--with the other character classes. Is this the cheapest way to encourage gamers to continue paying the monthly subscription that this game requires, or what?! Guitar Hero III--"Blowing It" (5G) If you are good at failing, then this is the perfect achievement for you. Fail a song 10 times and you've earned yourself an impressive 5 achievement points! Hopefully, nobody earned this one legitimately... Ghost Recon: Advanced Warfighter--"World Champion" (40G) To become the World Champion, all you need to do is be the best player in the world. That's pretty easy right? Ghost Recon: Advanced Warfighter--"Heavyweight" (24G) Rack up 10,000 kills via online multiplayer. If you can get at least 10 kills per match, you'll only need to play 1,000 matches, then congratulations! This shiny 24 gamerscore is for you! FIFA 09 - "The Peterson" (1G) How many gamerscore would you think you'd expect to get for putting at least 50 hours into FIFA 09? If you said 1 point, then you are correct! That's 0.02 achievement points per hour! FIFA 09 - "The Parolin Manoeuvre" (10G) This must be for the gamer who is 60 days late paying the Internet bill, and Comcast has just turned off your cable and Internet. You're logged into your profile, NOT connected to Xbox Live, and you've just won a match! Congrats here's 10 gamerscore! Trials HD - "Marathon" (40G)Trials HD is notorious for its high level of difficulty. If you can complete 24 levels, of varying difficulty, without a single mistake, then 40 points is yours. The achievement was tweaked in December of 2009 to make the achievement easier to get, by lowering the number of tracks from 24 to 20. Still it's a difficult achievement to master! Dead Rising - "5 Day Survivor" (20G) and Dead Rising - "7 Day Survivor" (20G) Upon completing Dead Rising, the player can access Infinity Mode. In this mode, the main character's health will automatically decrease over time. Food (health) does not respawn. The only way to increase your health is to find it or kill enemies who will drop it. Two hours of real-time is equal to one day of game-time. In order to unlock these achievements, the player must play the game without running out of health or dying at the hands of the enemy for at least 10 hours for the 5 Day Survivor Achievement and 14 hours for the 7 Day Survivor. Mega Man 10 - "Mr. Perfect" (30G) Complete the game without getting damaged. That's eight levels and eight boss battles, the five stages of Dr. Wily's Castle, and the final encounter with Dr. Wily himself. Do it all without getting ever taking damage and not only are you 30G richer, but you're also probably a God amongst men. Either that or you're insane. You're probably insane. But you're an insane person with 30 more gamerscore! Congratulations, psycho!
