halo 3 for multiplayer, Half-life for everything else.

 

Half-Life series, no question. Halo has this decade's worst level design (remember the library? Ugh).

 

I said I like them both equally, Half-Life for gameplay, Halo for the great story (counting the books).

 

Half Life, and including Portal because it refers to Black Mesa, making it part of the HL universe

 

Half-Life series hands down.
The original game was fantastic and ever since it has spawned so many great mods and spin-offs, from the earliest Counter-Strike to the totally pwning Portal. Of course the main line of HL games are amazing too and are getting better and better.

 

For the most part, Half-Life. But there's one critical issue that is pretty much used as a joke in Half-Life 2. Gordon Freeman is a scientist. And yet he just so happens to be a kick-ass one man army too? Kinda a tad weak there but for the most part, everything else is highly appealing to me. Including a bit of the new info about the G-Man in HL2 Ep2.

PS. Bought Halo 3 and The Orange Box. Why like only one when you can like both!

 

half life doesn't have a great story? youve got to be kidding me. you have no idea what ur talking about.

 

Halo got me to read Larry Nivens ringworld series, and for that im grateful But I also love Half-Life, and all the work they put into telling the HL story. One thing, I though HL ep2 was way too easy, atleast in normal mode. Gonna try hard later.
