Hi there!
I never realised people still knew about Magic World since I made it so long ago (and it was my first ever program), but I just looked on the showcase page here and it's been downloaded over 10000 times! Blimey.
Anyway, as promised, but much LATER than promised, the source code for it is now online. The showcase entry on this website has NOT been updated yet - for some reason I cannot access it - but you'll find it at:

... along with Total Terrain and a very early game demo. I'm not sure how much bandwidth I've got on my hosting company, so if a whole bunch of you download it my website may shut down! Hopefully I'll be able to access the showcase entry here and upload it here for you.
If people make the program compatible with current versions of DB, upgrade it etc, I'd love to hear about it. BUT!!! Please don't email me large files. Email me links to where it can be downloaded from, with a short description of the updates, and I'll put links on my website. Hopefully I'll still be credited for the foundations of the work on any updated versions!
My hope is that a group of you will take it on and update it together, but in any case it's yours now to do with as you will. Enjoy!
