Anybody have any game experience with the Concorde?
Is it worth buying one, or is it a gas hog that doesn't pay for itself?
Depends on the route and the competition.
For routes that don't have competition, it makes money. Other than that, I can't say for sure.
You can't buy the Concorde legally in this round, or the next. As for the round after, chances are the game would have changed too much that no one can predict it.
