I've always wondered why people like the Halo series. The game wasn't as good as they claimed.
Halo 1 was original, the game got harder if you were crap and pushed you into hard places when you were low on health
Halo 2 wasn't so great, you had a shield that charged up after a few seconds and no health bar in sight. It made the game incredibly easy. The multiplayer was an improvement on Halo 1 but because it lacked a health bar it felt like you just wasted your effort when you die since you would know that when you get back to your enemy they would be fine.
Halo 3 is the most annoying of all. You get your shield which recharges after a certain amount of time that was in Halo 2, but you also get items that can help you in the battle. Sure the items can be great for stratergy but when your enemy is invincible there isn't much stratergy except run away.
Why is this series so popular? Is it the straight forward story that don't give you any opinion on what you're doing? Is it the fact that your versing funny looking aliens? Or do you not really have any good reason for liking it apart from the fact that it is Halo?
There are many better games out there. Some FPS and some not. Most of them actually have a story that you feel like your a part of. Some of them include puzzle, which halo lacks.

WHY?
