You know you play Factorio too much when...

[AgentDove]

...you get a shotgun and kill all the worms and insects around you house.
...you build a giant wall with guns behind it around you house.
...you tell flying robots to take away the guns behind your walls.
...you tell flying robots to put lasers behind your walls.
...you press Q to put something down.
...you lure insects onto railway tracks.
...you throw robots into the air when there are worms nearby.

... complain to the airport staff that their conveyor turns aren't faster than the straight sections and are reducing the efficiency of luggage pickup.

You don't fear to walk past an electric transformer or poles.
You eat fish you just took out of the water.
You put your iron in the oven to have some plates.
You can't jump over a pipe.
You run over the luggage transport belts at the airport to go faster.
You carry a shotgun, a machine gun, both fully loaded. And a flamethrower. And a pickaxe. And it's PERFECTLY NORMAL.
You destroy houses for purple marbles because you need more alien science packs.

[Dysoch]

When you take your combat shotgun with piercing bullet magazines and start killing the neighbors because they might expand or attack you!

[Boogieman14]

when you find out it's today when you thought it was still yesterday (aka when you see the sun come up)

[DarkEnergy666]

when you destroy your house to put in a factory

[LordFedora]

When you and your roommate just built the rocket defense after about 12 hours working and defending only for the game to crash because it doesn't work in multiplayer, and then to realize it's 3am... and you both have an 8am exam

happens all the time
I played a lot of games, but this is limited to Factorio for some reason.

You find yourself looking for a new FFF on a Thursday night!

Monday ....

[Tnarg]

you go to bed with a problem and wake in the morning knowing how you can get the belts to fit.

[Deadly-Bagel]

You wake up in the morning and load up your game only you don't recognise it anymore because you made a new factory in your sleep.

[Koub]

You start a new topic when an old forgotten topic exists with almost the same title
[Koub] Topics merged

[brunzenstein]

Your happy your wife found a cheap divorce lawyer

[ChurchOrganist]

You toss and turn all night mulling over the train stacker you're designing to stop a train deadlock problem.

Then get up early and implement it!

[MarksmanKNG]

1) You build a task list to keep track of 'renovations' and construction modules and progress reports
2) You draw road maps on your map to plan your factory growth and expansion
3) You redo said roadmap several times due to space allocation
4) You realize you have nothing left to automate in Factorio for....5 seconds
5) You think of designing your latest set of automation while driving / at work / lunch & dinner

[Proxy]

when you are at a Trains Station and Criticize the Rail-Layouts.
