An idea that has been in my mind for a long time is to do a competition that spans the different civ games. I was thinking along the lines of one game of civ 1 - 5 and a Colonization & Alpha CEntauri game.
We could do it in a GOTM format (with spoilers for thos who want to). Big advantage over MP is that it's more time flexible.
I think Civ I & colonization are available as abandonware for those who don't own the CD anymore. Being the junk hoarder I am, I still have those readily available. Civ II would be a problem for me, my CD is lost I can only find my fantastic world CD
But I"ve seen cheap ass copies offered second hand so no problem there.
All the other games won't pose any problems I suspect. Would people play if we do this?
Also we could make it simpler and only do CIV 3 - 5 and Civ 4 - Col for example.
