For Christ's sake...
The Pratt Carrier line has set up a tourist route, using Luxury Liners to ship rich AND VERY STUPID tourists out to El Dorado, where they go wandering across the battlefield, into the ruined city, poking into sealed vaults and trying to buy souveneirs from the homicidal killer robots. Naturally, most of them get their heads ripped off, and then they complain.
... well... the ones that DIDN'T get their heads ripped off complain. The ones that DID get their heads ripped off don't say very much.
OK, that's it. I'm placing this planet under interdict. No more tourists. WILL ALL OF YOU IDIOTS JUST GO HOME???
I went into SM mode, removed the tourists to a different planet, and flagged El Dorado as a source of colonists instead of a destination. Since it has zero population, that should keep people away.
Idiots.
Very realistic! Eldorado is the new Troy!
