Well, in my personal experience, Negative traits in games don't work as well as you think they would.

Maybe everyone here has a lot better luck.
Regardless, my main issue was the silly Super virus, not the negative traits.
I don't even like fighting myself, but more XP to level up is a bad thing. It's the equivalent of "Small chance of causing nuclear meltdown in your cites" as a trait.

But as the old adage goes, whatever floats your boat. Plus, you know, you created it, StrategyOnly, not me. At least you listen to people, unlike Zappara.
And I'm not running into negative traits with no Negative traits on, I was simply mentioning the balancing of traits. I know, it's a weird thing to get hung up on, but it's me, guys, I'm insane.

See, I got the crazy eye and everything.
So, sorry to distract from the main concern, the Super Virus that doesn't actually kill anyone.

I'm just saying, -43 population is a bit much, when it doesn't even do anything.
I just think the event needs some scaling, because you shouldn't be able to select a -70 population option in a city with 46 population.
70 turns of rioting is a bit silly as well. "You killed 166% of our population!"
At least I didn't bring up the nuclear meltdown on things not nuclear powerplant related.
I know it's a bit minor, but it basically prevents you from building those buildings for obvious reasons.

Okay, so I did build the Toxic Waste Dump in Hackensack, no, I really did name a city that. Wouldn't you do that too?
Just saying, exercise in tediousness doesn't punish people, it just makes it annoying.

And we all know rebuilding buildings after a nuclear meltdown is more tedious and annoying than anything else. IS there like a XML option I can change?
It's like how the electric fence, cement barrier, and even metamaterial barrier causes -1 to trade routes. No one will ever build that.
It could give like 100% to Production of Megatowers, and no one would still build it.

IT could cure all unhappiness and unhealthiness, and give like 200 food, and still, no one would build it because of that -1 to trade routes.
I mean, unless someone thought, "Hey, I have way too many trade routes. 80 is too many." I can't see any reason for building them.
Also, thanks for adding more air pollution reduction buildings. I know that was added a bit of time ago, but thank you.
Also, is multiple maps in this yet? I see mention of Mars colonies, but the Lunar Rover can't seem to go to the moon. I could have sworn I built the Apollo Project, or did you put that in like "Advanced Superstring Theory."* or some late game tech.
*I made up the name, I can't remember all the late game techs.
Bottom line, I'm still crazy, you try to change your brain, it's not easy.
I thank you for putting up with me for at least 4 years.
Oh, and thanks for removing the Catacombs of Trolling. Now if only we could convince Grimith to play this again.

Oh, what do normal Catacombs do. I noticed once my enemy went into my city and started killing people, apparently, but that didn't do anything else.
