really? they are making you buy it? i tryed dl'ing the demo, but those no longer work. but anyways, i bought halflife, and when i activated it on steam, i got all of the hl1 things for free. cs1.6, blueshift, opposing force...EVERYTHING! and i didn't even own any of them...hmmmm....oh well, i'm not going to argue. but anyways, yeah i don't know why steam all of a sudden wants money for that game again, even after installing hl1. maybe it came with that last update that tempts you with "pre-load complete" i don't know...
