Halo games on easy difficulty. People consistently claim they want old style 90s shooter action, including yahtzee. Well, guess what? On easy difficulty, you become a bullet fridge who can jump high, run fast, and punch aliens to death. It essentially becomes duke nukem, albeit with an energy shield and a 2 weapon limit and regenerating health for 2 and 3. Not to mention, it's just plain fun killing hundreds of evil religious aliens. It's cathartic as all hell, plus the aliens like to say funny quotes too. There's a reason combat evolved had 4 sequels, 6 counting halo 4 and ODST. It's just plain fun. Childish, stupid, indulgent fun. And you know what? Sometimes, that's all I want. To punch aliens to death with a smile on my face.
