+
+On a serious note...
+
+As a former POW (Vietnam), I hesitated to play WOLF for over a
+month after downloading as I feared flashbacks.  I didn't want to
+remember all that I had been through all those years ago, when, as
+POW's, my friend and I decided an escape attempt would be better than
+a slow death by torture and starvation.
+
+My friend and I made crude maps and hoarded food. The day of the
+escape we clubbed the guard with stones, took his gun and fought our
+way through two levels of underground tunnels (only a few guards and
+had to crawl).  I made it, my friend didn't.
+
+Dreams...NO!  NIGHTMARES...YES!!  However, the more I play
+WOLF the less frequently I have nightmares.  The chilling part is
+turning a corner and seeing a guard with his gun drawn.
+
+WOLF is a powerful game.  Fearful as well.  I believe that a
+person should face the past.  So... when I can play EPISODE 1
+comfortably (no nightmares), I plan on ordering the full series.
+
+Don't let a few bad dreams make you discard this game.

+
+Jay, just thought I'd drop a note to let you know how popular Wolf3D is
+here at Microsoft.  It seems like I can't walk down a hall without hearing
+'Mein Leben' from someone's office.  I hope you guys are getting revenue
+from all this.
+
+Anyway, we were sitting around talking the other day, discussing games for
+Windows, and someone said 'What are those cool guys at Id doing?'.  So how
+about it.  Are you guys looking at Win games at all?  Win32?
+
+In a perfect world, I'd have you guys port the Wolf engine to a multiuser
+maze game for Windows for Workgroups.  We need a good M'user Win game.
+
+Anyway some thoughts.
+
+Ty Graham (Microsoft)

docs/release.txt

+We are releasing this code for the entertainment of the 
+user community.  We don't guarentee that anything even 
+builds in here.  Projects just seem to rot when you leave 
+them alone for long periods of time.
+
+This is all the source we have relating to the original 
+PC wolfenstein 3D project.  We haven't looked at this 
+stuff in years, and I would probably be horribly embarassed 
+to dig through my old code, so please don't ask any questions 
+about it. The original project was built in borland c++ 3.0.  
+I think some minor changes were required for later versions.
+
+You will need the data from a released version of wolf or spear 
+to use the exe built from this code.  You can just use a 
+shareware version if you are really cheap.
+
+
+Some coding comments in retrospect:
+
+The ray casting refresh architecture is still reasonably 
+appropriate for the game.  A BSP based texture mapper could 
+go faster, but ray casting was a lot simpler to do at the time.
+
+The dynamically compiled scaling routines are now a Bad Thing.  
+On uncached machines (the original target) they are the fastest 
+possible way to scale walls, but on modern processors you just 
+wind up thrashing the code cash and wrecking performance.  
+A simple looping texture mapper would be faster on 486+ machines.
+
+The whole page manager caching scheme is unecessarily complex.
+
+Way too many #ifdefs in the code!
+
+
+Some project ideas with this code:
+
+Add new monsters or weapons.
+
+Add taller walls and vertical motion.   This should only be 
+done if the texture mapper is rewritten.
+
+Convert to a 32 bit compiler.  This would be a fair amount 
+of work, but I would hate to even mess with crusty old 16 
+bit code.  The code would get a LOT smaller.
+
+Make a multi-player game that runs on DOOM sersetup / ipxsetup drivers.
+
+
+Have fun...
