Here is a direct quote from John Carmack's recently updated blog: "There are still bits of early Quake code in Half Life 2". I loved Half-Life 2, great game, but I found it interesting that there are still pieces of the ORIGINAL Quake in HL2. I wonder what technology in the engine he is referring to, and how he got this information since he doesn't work for Valve.
