From your examples, Half-Life was great, but the graphical difference from HL1 to HL2 certainly contributed to improve the experience. There's nothing saying that we can have either good gameplay XOR good graphics. Both at the same time are nice too.
While the unlocked graphics style is certainly better for screenshots, it suffers the problem of highlighting close things, while highly blurring anything at a distance. While more 'realistic', if I were testing the game, I'd definitely suggest disabling this 'feature' by default, as it really can hamper gameplay and discovery.
That's pointed out in the end of Total Biscuit's video. There's still stuff to enable/bring back, and stuff to adjust. He plainly says that the depth of view effect might be too much in this version of the "mod".
GNU Pascal is a frontend to gcc: it takes the pascal input, translate it in some intermediate language that gcc can understand, and let him finish.
This mean that FreePascal have to be designed to produce outputs for all platforms, while GNU Pascal only have to follow gcc evolutions, and is instantly able to build on all supported gcc targets.
To summarize, they are different software for roughly the same purpose. I believe that more details will make it technical
After having played with a surface tablet and an "embedded" windows 8 computer (those things that combine the computer and the screen), I can tell you this about the touch features: they are broken by design, gets in the way of doing things (even moving a file is more complicated than using a mouse, and why doesn't the keyboard pop up when hitting a textbox?), and as such are useless for everyone, not just the cube farm drones.
Anyway, for reference, although not technically like the original, there are open-source projects that might be of interest:
- http://clonekeen.sourceforge.net/ (GPLv3)
- http://clonekeenplus.sourceforge.net/ (GPLv2)
I tested the second one, and it handle the original game files (available through steam) pretty well. The first one might, too, but I'm way too lazy to build it right now.

GNU Pascal (GPC) is a Pascal compiler composed of a frontend to GNU Compiler Collection (GCC), similar to the way Fortran and other languages were added to GCC. GNU Pascal is ISO 7185 compatible, and it implements "most" of the ISO 10206 Extended Pascal standard.
