The second edition of On Tour now supports 8 players out of the box (instead of 4 in the first edition). A second copy of the game will support up to 16 players. The map boards are double sided featuring the US map on one side (the one from the first edition) and a map of Europe of the other side. The European map has the same rules as the USA map, but the differences in geography create a different feel and strategy. There are fewer connections on the European map (70 lines for 39 countries vs 89 lines for 41 states). However, it is easier to get from one side of the map to the other on the Europe side. The max distance between any two countries is 6, vs a max distance of 10 on the USA map. So on Europe, it is easier to zigzag around the whole board, but harder to wiggle around in close quarters. The European Expansion is also available by itself for those who do not wish to purchase the second edition. Other changes to On Tour include: The new box will be about half as thick. Around 2 inches tall instead of 4 inches tall. The maps are changing to be a little bit smaller, a little bit thinner, they will be folded in half instead of thirds, and won't have the decorative tape binding.
