Martin, I just wanted to say you've built something awesome here. I'm the player Vheissu you might see who has been topping the leaderboard. I would love to help you expand upon the game and make it even better. I'm a bit addicted to it, but think being able to have other avenues to expand the mechanics would be awesome (think maintenance costs, fuel costs, market volatility around fuel, etc). If you're down for a collaborator, I'd love to get involved. It's got a lot of potential.
