What the... ? A publisher actually listening to gamers? What's next, good customer support?
Go Digital Jesters! Woo!!
I voted DVD*, but only recently did I finally put a DVD drive in. The Europeans seem to be way ahead of North America in making DVD drives standard PC equipment, so I wouldn't be surprised to see voting trend along those lines. Since DJ is Europe themselves, might help to know where the CD voters are from.
*Assuming, of course, that you can avoid the technical pitfalls of a lot of other DVD games - Myst 4 being the most recent.
