I played the Map mode and got the same page several times, and then the game ended with half my "life" left. It was really fun but I passed a lot of rounds just on memory
1. Europe has a greater emphasis on welfare and has greater social saftey nets
2. US private healthcare makes it harder for the poorest in society to get drug-related issues cared for
3. US War on drugs being a historical political selling point to gather voters
4. Private prisons; lobbying for stricter drugs laws equals profit
5. Over-prescription of pain medication by US doctors; lobbied by pharmaceutical companies for profit
Some of these points don't apply at all to Europe, or do with much reduced impact.
