Starting my Ice Castle now! 

Thank you Daz!

Since Quaddicted is not available right now, here is an archive link to use in the meantime for the texture wads.

"* The map can be any quality level (speed, turtle, full detail)"

What's speed, turtle and "full detail"? 

Must be a regular SP map, no multiplayer, no mods? 

So ... it's unclear. There ARE WADs for this or their aren't? I'm thinking not but ... 

*there

Fuck. 

typically the jams are vanilla quake.

Speed map = 24 hour map
turtle map = speed map but a bit longer to make (id software quality)
full detail = intense detail, mfx/sock/tronyn/skacky etc 

there's some wads above in the OP. I think it's a loose theme, those are suggested. As long as it follows the fire and brimstone theme (some of the reference shots are base themed) 

historical note: "speed map" used to be 1-2 hours 

There ARE WADs for this or their aren't?

There are two wads in the download for you to use. You don't have to use them, and you can use other textures of your own choosing as well!

Single player, vanilla Quake! 

Speed map was 1 hour, then extended to 100 mins. Then extended to as long as you wanted, since that's how long people were taking anyway. 

I vid a video about it too https://www.youtube.com/watch?v=qTkCht6nkU0 

Turtle map was 1 week. 

I stand well and truly corrected then...

I wouldn't be able to make a decent map in an hour that's for sure.

Mapping and Black Metal. 

I'll likely do a few small informal streams ... maybe. :)

That selection of inspiration images is fucking brilliant.

Anyone who does this: http://daz.fov120.com/images/jam6/theme2.jpg i will marry them.

Nobody could. That's why it was extended :) 

What about them?

Or better: what's the target engine? 

I should have added something about that to the main post, but I think it is generally assumed that most people use FitzQuake / Quakespasm these days.

I would test all the maps in Quakespasm as that has the most up to date features. 

Also, don't forget ...

If you're so inclined. :)

Actually, the switch to 100 minutes came when everyone wanted to do more single player maps. 1 hour deathmatch maps weren't so bad to make, but we added the extra 40 minutes so that single player maps could reasonably be done.

Back on topic, I'm planning to do a Rubicon Industrial base on a Lava world. 

I miss those speedmaps, people were experimenting much more, probably because the time investment was so little. 

Is it good if I make a modern city with red sky on its first part and then having its second part filled with lava and brimstone?

Or should I just make a map just like the second part?
