I've finally reached 150 + skill stars 👍👍
Congratulations! I have 128, so I will join you soon.... I hope
Past first like 100, 110 it starts to get tricky, since you either have to fly some routes that you don't want that much, or you buy bigger planes... which makes you a target for worse alliance missions to annoy you. And given that alliance missions often have 250, 500 and 1000 for stars... yeah.
