When I was completing Half Life 2 I was just thinking to myself "I love how idiots just latch on to Halo and just say every other shooter is better even though it doesn't have any of it's own qualities to it."
Seriously, they only like halo so, here let me get up a quote from someone...
CAUSE' YOU GET TO BLOW UP ALIENS! >:D
Obviously, you can do that in any other game that includes an alien race. If you go to play another good shooter, you will come to find it most likely has a great story, great gameplay, some form of aliens, zombies, or solider you get to blow up, and maybe some of it's own content that any other game doesn't have.
I'm sorry guys but Halo is an uncreative game and is a lot worse than any other shooter.
And another funny story, I told some funny quote to one kid and he got ticked. This was the quote:
Gordon Freeman: Screw Master Chief with his assault rifles and rocket launchers, all this guy needs is a crowbar!
He started going on and on about how Master Chief was better and that he could too go through the game with a melee weapon, yataa yataa.
