You've been playing Wesnoth too long when...

[Dunno]

515. When you make Wesnoth: The Movie by writing a replay from scratch.

[sur.nhm]

516. When You roleplay Wesnoth characters. (I do.)

[Drakefriend]

517. ...you think every sufficiently spectacular special effect is made by Inferno 8.
518. ...you try to figure out whether Arabians are Kalifa or from al-Kamija and if Feudal Japan played Descendants of Dragons, Emperor's Guard or Blades of the Rising Sun.
519. ...you want to look something up, you use Debug and look up it in the Help. instead of e.g. Wikipedia.
520. ...you think reproduction works by recruting from a keep.
521. ...you are the only person in your village/on the mountain/on the bridge/etc
522. ...your house is as large as a village.
523. ...you try to recruit own units in your enemy's basis, just because their commander has left his office and there is still place in there.

524. You browse some other forums, and you click on a thread and begin reading. About halfway through you begin wondering, "This guy's such an idiot. Why hasn't shadowmaster locked the thread/banned the troll? Oh wait.." Lather, rinse, repeat.
(true story, in a sense a true testament to how well shadowmaster has been taking care of the forums. That made me realize this.)

525. You get a promotion of any kind on the Wesnoth Forums.
526. You think new people join the forums and then find out it's only elvish_sovereign (This will take some getting used to).

527. Your desktop background is the Wesnoth map.
528. You have changed all your icons to images from Wesnoth (recycle bin--ancient lich. Computer --> Dwarvish arcanister, etc.)

Guilty on both counts.

You do play Wesnoth too much

[Iris]

529. You know that letting a YHBPWTLW thread live for long makes people start posting unrealistic nonsense entries.

[Frogger5]

Uh, oh. I can feel the shadows approaching.

[Drakefriend]

530. ..you think Wesnoth players are the only people important.
531. ...you think Wesnoth players are the only people in existance.

532. ...you write a "historical" novel based on a Wesnoth campaign.
533. ...you write a "history book" based on a Wesnoth campaign.
534. ...you were a history teacher before starting to play Battle for Wesnoth, and get fired because you only teach the history of Wesnoth.

535. ...you can imagine anything listed above without having to read it ...er, but have kept it to you.

PS:
536. ...you feel personally offended if someone makes any amount of fun of Wesnoth.
537. ...you don't say "WINR", but "RINW".
538. ...you cannot understand how someone could come to a such absurd claim as Reality and Wesnoth not being the same.
539. ...you wonder why everyone says we were on "Earth"- the planet's name is Irdya, you idiots!
540. ...everytime you are hurt, there is a number flooting in the air, however, no wound has any ill effect until your hitpoints reach zero, and poison cannot kill you.

[Mountain_King]

541. You start to think you might be agreeing with shadowmaster on this one....

[Shield]

542: You spend more time playing wesnoth than sleeping.
543: You start dreaming in wesnoth scenarios.
544: In a dream, your favorite wesnoth character/unit tries to kill you and all of your friends...
545: ...but in a later dream, that same character is your best friend... who is killed in a ridiculous manner.
546: You start noticing that common household sounds sound like various unit attacks.
547: You lose a campaign... but dream up the rest of it later.
548: You hear wesnoth music in your head when you're near your wesnoth-playing computer.
549: Orcs attack you in your dreams.
550: You actually consider making graphic novels based off of the campaigns.

All of these have actually happened to me!

[Crendgrim]

551: You think about how many YHBPWTLW entries are existing twice and more times.

[Dunno]

551: When your computer stops working, first thing to come to your mind is you won't be able to play Wesnoth
552: + when it happens, you look for help on Wesnoth forum instead of Computer-stuff-related one.
