I was thinking about picking up D20 Modern. I have a quick question though. Does it have rules for overland movement and weather rules like D&D? You see, I don't have my D&D books any more.
d20 Modern have rules about environments and hazards.
d20 Modern does not have rules about overland movement. It's the GM's discretion, especially when PC may have or recently acquired other means of transportation than just walking, in the modern time period setting (i.e., cars, buses, airplane, etc.).
HOWEVER, you can download the 3.5e SRD -- if you're in need of calculating overland movement -- from the Wizards' web site.
