We make bad suggestions and come up with horrible ideas.

[giannikampa]

there is a chance that at the beginning of an enemy raid they say "what a lovely place, we'll join this colony in mass instead of attacking it", and so it happens.

Rap Battles. 

The loser catches on fire and burns to death in seconds.  The winner gets a 2,000,000,000,000+ mood boost.

Also lawnmowers

[mumblemumble]

Allow heavy base music. music causes hearing loss in colonists around it, but provides joy, particularly to chemical interest people.

Music increases chance of nearby machinery breaking down by 50%, due to the heavy vibrations rattling loose nuts and bolts.

also has a chance to make nearby animals go berserk.

And nearby teetollars or colonists above a certain age.

[Names are for the Weak]

You know the Zzt event, where your batteries short circuit and burn everything? I think that it's too rare. I say that it should happen at least once a day, with no way to disable via scenario editor. Same goes for blight. Actually, now that I mention it, blight should also affect harvested crops, where you lose a majority of your potatoes, rice, etc. after a blight. While we're at it, it should also affect meals with plant matter in them as well. And electronics ought to break down immediately after you replace the components within. You know what, even non-electronic devices ought to break down. Yeah.

Your version of the blight is for the weak.

A true blight would target humans and make ~80% of your colonists blink out of existence without any warning.

Necromancers like in DF whom can ressurect fallen raiders and often come with their own zombie armies.

[SpaceDorf]

Necromancers like in DF whom can ressurect fallen raiders every corpse and severed body part on your map and often come with their own zombie armies.

if you say like in DF ..
( and yes I mean the special loot stockpile next to the hospital. )

[ARiA1089]

a jumping puzzle

[Cheeseguy]

Add an event in which you've somehow angered Zeus, causing staggered lighting strikes on all of your colonists.

This.... This is gold. please tell us more I like this, ANOTHER!

[Lowkey1987]

Doors work well. Lets change this!

Sometimes doors can get jammed and stay the way they are!

Want to go back in, because a manhunter pack comes in! Ohh the door didnt close?
Want to go into to the hospitel to help your wounded pawn (which fight off a manhunter pack). Darn, the door jammed!

Make a small notification "Please call the maintenance man".

[Vlad0mi3r]

Pawns should have the chance to suffer from PTSD (Post Traumatic Stress Disorder) after each fight/raid. No notification is given that the pawn has PTSD until drafted and a weapon is used within 200 tiles of their location.

Results could vary from attacking your other pawns to charging into hand to hand combat with the closest opponent to going to hide in room mental brake.

[Lowkey1987]

Someone says "We need Bones as material"

We already have corpses. Lets make walls out of them!
After they decay in summer...

Mine them for bones!

[Call me Arty]

Insects should have giant "thinking" bugs that spawn when they get a few hives going. These thinking bugs make them actively wage war on your colony.

Dude that's actually kinda awesome.
