a bad board simply because absolutely no strategy is required to play it. there are two sides, separated by a border in the middle. If you win, it'll be from luck, not skill
Fun for team games, and incredibly creative. i still may never fully grasp all the strategy behind it, but i'm sure that there's one out there that'll lead to a better chance of winning.
Same board as invention except without the research and tech points. The only difference between this and normal risk is the capitals.
Great for people who like invention, but wish it was faster
The cards and elimination bonus make it easy to put together a chain of eliminations, but there is a big "race" at the beginning to claim a bonus or two first!
