This is and epic desicsion that only the game makers can choose. But i may have to say that half life took it because of its great story line and awrds achieved.

Im gonna have to go with bioshock. It just has a better plot, plus you get to be on both sides.

I love both but i would have to go with Half-Life. Just cause both Bioshock's story lines are stand alone. Also i have played Half-Life longer :D HL FTW!

bioshock. hands down. no contest. but still, half life is an awesome game.

Half life no contest. As good as the story is for Bioshock its on a small scale, in half life gordan freeman is freeing his ENTIRE SPECIES from extinction at the hands of an alien race.

half life no doubt

Oh god... this is a question to be questioned.

Question is impossible...
Half-Life hands down...

Played neither but Half-Life 2 = Portal, so HL2 wins :D

bioshock felt like "time splitters: on PS2 (the way it controlled). the story was cool, but the game was so easy it couldnt hold my interest.

half life 2 had cool mods, (gary's mod, portal, etc), new episodes, etc. and when it first came out, youre lieing if you werent amazed by the physics. terrified by ravenholm...

cmon: gravity gun, super gravity gun, laser guided rocket, big walking stick bugs ravaging the city, the awesome physics puzzles, ... experimenting with the physics....

to me its no contest... but alot of people i know loved bioshock... i could just never figure out why.

Half Life ALL THE WAY!!!

Bioshcok without a a second thought

NO! Bioshock wins hands down! The story line was really good and it just seemed way more fun to me than half life.
