I wonder what Fabien Sanglard would think of this. To me, the Quake 1/2 source code has been an invaluable source of insight, as much for small algorithmic stuff (like collision/sliding code) than for its architecture as a whole (like game/engine separation, the edict_t system) ... Have you never asked yourself "how did they do this" ?
