Guns of Icarus Online. In my defense, I was trying to do what my ship was designed to do. The co-op mode on display is all about delivering supplies to a final point on a map, and I was flying the fast scoutship. So I figured, why bother slowing down? Why not just jink left and right and avoid anything in my way?
As it turns out, the reasons to not do that are quite simple: The boss encounter at the cargo dropoff requires two people, and you need to actually retain control of the point rather than just wing to it at full speed. So I may have sent my ship crashing to the ground in a tumble of burning wood and broken steel. (By "may have" I of course mean "I definitely did this.")
This isn't a failing on the part of the game, just a failing on my part for trying to bull-rush through something. But it's still fun; the game gives players a variety of things to do while they're busy crewing the various stations across the ship. And it's just one place the developers are going with the game.
