The idea of global warming being bad for crops is one I've never understood.

Weren't the warm periods and the very high temperatures of the Cretaceous also bunker times for crops and plant growth in general?

The newer systems make all three of the original Civilization games (Sid Meyers) so much better. on my 133 system on the largest map size the computer turns could take as much as 15 minutes. now I finish them in under a minute. makes for a much better and more involved game all around. The Quest For Glory series by Sierra are also still great games, and now I can turn the graphics all the way up
