Remix and add more upgrades and interstates (the next one is Interstate 73). Interstates must be in order and when one interstate is done, another starts. They are measured by mileage in this game. Change Log: Version 60a: Added things that increase chance of helicopters and other stuff, but isn't complete. Version 61 (also V60b): Put the new buildings in a permanent spot and added a splash screen Version 62: Added music, finally. Version 63: Added the Select Mode button Version 64: Music volume can be adjusted with the W and S keys. Rules (they go for all game items): 1 and 2. Those rules in the instructions. 3. Please, do not change, delete, or get wrong highways (INTERSTATE 1 DOES NOT EXIST). 4. Existing or if you must, future, MAJOR highways only 5. Helvetica only for Interstate number fonts, please. It looks the most realistic. 6. Please don't change the background. 7. Not all highways should give research point frenzy boosts. Alabama gives a frenzy boost!
Credit to everyone.
