This game is great, but there's way too much grinding on later continents. I'm pretty irritated by the fact that I can't sell my old plane and bring my money along to buy a similar model. I end up with the same old beat to crap six-seater and $1000. The new planes need to be unlocked at higher levels, which require a lot more experience to complete. I don't even get new plane technology, it's just the same stuff over again.
Great game until you get bored of grinding.
Autosave failed to update after 48 hours of play. Twice. I even manually pressed the Save button the second time, and it still dumped me back to my saved character from before.
