I believe you can make parts of half-life 1 in FPSC, things like the creature in the blast pit, it can't see it can only hear. Another thing is the flying helicopter that drops off troops every 1-2 minutes in the outside level. While parts of hl1 is recreatable in FPSC, some are not, without a mod that is. If you modded the source code yourself, and added more features and functionality, or you completely rewrite the source from scratch, you could make hl1 or hl2 for that matter, you could make anything, it just how you mod the source. But, in stock FPSC not all of hl1 is possible, but some parts are.

In a way, project blue would do miracles with outdoor environments, and large amounts of enemys, while ply's mod would be useful for scripting. In stock FPSC, I can't see all of hl1 possible, only parts, while with a mod, more is possible. But if you created your own mod which adds features like more AI commands, script commands for AI to not only see but hear as well, particle effects, water, and more general functionality, you could remake hl1.
