I would love a Mac version, at least of the first 5 games. They were Dos games right?

Since they were DOS games, you can just use WINE to extract the installer and a Mac version of DOSBox to actually play the games. I have played the games this way on Linux.

(The CD version of World of Xeen may require some tinkering with the dosbox configuration to run because of path differences between the OSes.)

I don't know. I kinda feel that I'm buying stuff from here to get rid of all manual bother. I bought the game when my primary computer was a PC and have now switched to Mac.

Well, sure. Do keep in mind the issues are not technical in nature. Which means they are legal. I doubt those will be resolved anytime soon. If you want to play them in the next few years you might want to go ahead an get this running yourself.
