Today, I got my ass handed to me on a silver platter.
I decided to go explore the Alpha Centauri system with a deep-space Geosurvey ship. I was overexcited to see that there was an almost earthlike planet that would be easier to colonize than Mars, so I sent the surveyer to check it out for resources. Turns out it was inhabited by some aliens who didn't take too kindly to my poking around, so they fired missles at us that immediately destroyed the surveyer.

The surveyer got some decent information on some ships that were in orbit of the planet, and it turns out this alien race prefers small and crazy fast designs (not shown in the screenshot though) that carry mostly missile-launchers. I decided to test them, and sent a squad of cruisers their way that were armed with beam weapons and plenty of anti-missile missiles. Just as I thought I was winning, TEN other alien ships appeared out of nowhere (cloaked or came from another jump point) that were going 10,000 km/s and obliterated the fleet in 10 seconds flat. I don't think I will be going back there anytime soon.
