I have played exactly one game on this board and found it delightful. Easy to pick up the rules, which also fit the theme.
Clicking on the balloons can be a bit tricky for those us who frequently play on mobile, and imho it doesn’t quite make sense for the balloon borders to exactly match the land borders (looking at you, Canada) but that’s the limit of my criticism.
I am interested to see how people adapt strategies to this board, which looks standard vanilla Risk but is not standard vanilla Risk.
