I have played and love Half-Life, but the replayability isn't the same. I know a level from the inside out when I play it twice. I'm more interested in direct battlefield situations and sneaking past floods with my active camo (mwehehehe). It's a matter of taste, it always is. People whine about this game is better or that game is better. I just want to let people know that there is no "best game". Only bad, ok games, and good ones. And unless Halo was a ripoff off of Half-life in gameplay concept...
I Have all the battlefield games! That one is my favorite! I love the poison cakes you leave on the ground then an enemy comes and eats it!! it's not very balanced though because sparaticus can jump around and sh*t so it's impossible to hit him.
