Fuck yeah.
CotW is the best Windows 3.1 game ever made. I have the same saved game that I've been playing for about 10 years now (not so much any more, but I still play it for 30 mins now and then).
I'm about level 27, max everything with about 12 billion copper. Sometimes when I get bored of a dungeon level, I press shift+] (I think) when going down a staircase so that the level regenerates (SECRAT DEBUG FEATURE
)
You can get CotW2 for free now (it's legit abandonware), and for a while, the author would send you the source code if you asked him nicely and talked programmer for a while.
The source is essentially useless except for some of the algorithms (random dungeons, etc).
