Aperture Science is much better. Black Mesa got the world taken over. Not Aperture Science. Aperture Science has portals. Black Mesa's got a wimpy gravity gun. Aperture's even got a hilarious robot. How can Valve come up with with both of these companies? Even after I explained how much Aperture is better, you can show that Aperture is better by voting in the poll above. Its almost pointless because Aperture is just so much better.
