A completely recreated version of Advanced Civilization w/fantastic all new art. There are people such as printplayproductions.com [1] who will make one-off copies of prototype games on request from sets of files, but will probably run you in the $150 to $200 range. This is the copy I have.

Currently available in retail boardgaming outlets, very deluxe and very huge. Extreme boardgaming. Retails around $250.

Both of these versions come with all of the expansions and supplementary material, and Mega-Civilization comes with a lot more, driving the maximum player count up to 18(!). Both options are cheaper than trying to accumulate all of the original material on ebay, and the components are nicer.
Just trying to be helpful...
As much as I enjoy Advanced Civilization, it does take a long time to play; lengthening it even further and getting more people together doesn't really help.
I'm a partisan towards the redesign, probably because I have it (had it made at printplayproductions.) It's really gorgeous and the components are very high quality, and there are no differences in play from the original, other than the errata are fixed. He makes a lot of them, so the turnaround time will probably be negligible. This is how the redesign looks.
