What Hacker News says

18 sources
I didn't say they were wrong, I said they were not high-quality. Every company works in their own way, but I highly doubt the original source would have a big paragraph at the top instead of a more "structured" comment. Or maybe even nothing at all! Here's a "counterexample": the pistol code for half life 2[0]. Comments are pretty sparse because it's all relatively self explanatory. The comments that are present are to point out things that are not so. You end up with something that's easy to work with and where you're not trying to read a paragraph of text that enumerates a bunch of properties of the code in the file in no particular order. Some things are important context for the whole file. Some things are important context for a fragment of code. Some things ... are simply not that important to note.

In Resident Evil 4 (GameCube) – complete byte-identical decompilation to C/C++
By reading these comments on hackernews , I came across the bug report of asking source's code https://github.com/ValveSoftware/source-sdk-2013/issues/624 it was heavily disliked by people. So I think I have come across the solution of crowdfunding. I have presented various benefits to the crowdfunding & I am writing this again so that this can be a comment of its own so that it can be much more easier for hackernews people to see I suppose for better discussion purposes I suppose. https://github.com/ValveSoftware/source-sdk-2013/issues/624#...
In Valve releases Team Fortress 2 code
I had quite some pleasure working with the Source Engine gameplay code. (Some 10 years ago now) https://github.com/ValveSoftware/source-sdk-2013 It is not that the quality of the code is high, but just that it is well organized, and everything seems like it was written by a beginner. That makes it wonderfully easy to read and follow the logic. Since have played around with the Source Engine, I follow the KISS principle with coding with high priority. Rarely trying to be clever, or try to over-do abstractions.
In Ask HN: What's the best source code you've read?
Valve uses their own tier0 and tier1 libraries in both the Source Engine and Steam, they implement their own standard library like functions and I believe it's where the memory allocator is too. tier1 source is available [0] whilst I don't think tier0 has ever been made public, though it's headers are [1], if you look hard enough you can find the complete source code for Source 2007 though which will include tier0.

In A Remote Code Execution Vulnerability in the Steam Client
I've played an unhealthy amount of HL2 and spent a while modding it, and I don't believe this is true. People say things like this a lot about games with decent AI. For example, the old quake 3 hoax about bots "learning" to become peaceful on a server that was left running for 4 years. It's fun to imagine the AI as more than just a set of scripts. The Valve Developer Community has some okay documents about the AI [0], moddb has some nice articles too (no links offhand). And most of the source for combine guards is available in the Source SDK [1], you can see tons of if's and hard coded sequences of actions. I've read that the AI was changed after the Orange Box release, so maybe there was some learning features to them originally. Or maybe those features do exist within HL2's private source files, though it doesn't "feel" like it. [0] htt

In Integrating GTA V into Universe
"The source for this new SDK release includes the latest code for all the included games, and has many new features: • The games now build and run clients on Windows, OSX, and Linux. Dedicated servers are supported on Windows and Linux. • Steam Pipe (the new Steam content delivery system) is supported by the sample mods. Existing mods can change their gameinfo.txt to match the new format and gain Steam Pipe support. • Support for Virtual Reality via the Oculus Rift has been added to the SDK. Running a compatible mod with -vr on the command line will run the mod in stereo and enable head tracking on the Rift."
