I'm curious: are most new/current users using Steam? Or GoG or something else?
I played Civ3 in 2007 when I had some more time on my hands than usual. In those days of course I bought the CD to play on the computer. Eventually I couldn't stop playing and needed to actually throw the discs out so that I could get back to more productive use of my time. Then a few months would go by and I would buy the discs again, play for a while, and have to throw them out to stop. I did that maybe five times until I finally kicked the habit.
Then sometime last year I somehow got connected with the CivFanatics website and especially the Game of the Month. That turned me on to the game all over again. Now I could play the same game as others and talk about it, compare my progress, and add some meaning to the individual game I was playing. But you can't just walk into BestBuy and purchase the discs anymore. Civ3 might be the same as it was in 2007, but the world is different.
tjs282 and
cks (?) were a
huge help to me in overcoming the technical difficulties I had getting the game up and running and becoming able to actually play the game of the month, but I eventually got there.
What I needed to do to play the GOTM for
Play the World was buy the discs on eBay. That was difficult as I was confused and bought the expansion pack without the base disc or vice-versa a few times, but I eventually got the right combination. Then I needed to add pediacon files and do a whole bunch of other things that were way above my skill level, but with the help of tjs282 and cks I eventually got Play the World up-and-running, was able to play the game, download it, and share it.
Civ3
Conquests was easier in some ways. I opened a subscription to Steam and then the game was available through their network. I still needed to download it, but I didn't have to add any extra files if I remember correctly.
Getting a computer to use for the game was another difficult issue. None of the computers I had would run the PTW discs because the software was obsolete and I didn't want Steam on an office computer. Fortunately I still had my desktop computer from 2007 laying idle in the office and that is the one I use for Play the World. For Civ3 Conquests, played through Steam, I use an old laptop also from around 2007. It has the software that is compatible with the game and I use it for nothing else. It is my Conquests Laptop.
