Ascending Empires by Z-Man Games is a 4X space game...
The tagline from Alien told us that in space no one can hear you scream. Ascending Empires tells us that screaming isn't the only thing that no one will hear: In space no one will hear you when you try to explain that the spaceship you just flicked into their orbit got there purely by accident. You had no intention on going anywhere near them, and that you didn't mean to hit that planet that ricocheted your ship right into the heart of their sector of space. Yes, Ascending Empires has reminded me of this cruel fact over and over again, and that any such "accident" will be treated as nothing short of an act of all-out war.
