Void jam

for those lacking ideas 

Yeah, that was something like I was thinking. I didn't really spend that much time coming up with the words, I'm sure there's plenty more possibilities.

I tried to avoid words that were too style-restricting such as Gothic/Medieval/Egyptian and those that might require new, or a specific type of, textures such as Fire/Gold/Frozen. No reason they couldn't be used though. 

i.e. czg's pants. 

At least judging by the number of speedmaps "czg's anus" produced... 

Void maps. Isn't that what "Coagula" maps are? I've always liked those for some weird reason.

I made a ctf space map for Q3 once. Never got around to putting the final polish on it though. 

 

Verrrrrrrrrrrry long overdue. 

How about Techno Egyptian? 

Just Egyptian/Temple themed. 

Egyptian/temple could be fun. But hopefully there is a little more downtime between the last jam. 

... unless there is a total Blood, Gore and Gibbs, Texan Style Fest ! 

Techno Viking theme

ps
Egyptian/temple => steal textures from Hexen 2 and Serious Sam 

I've been bangin' my head against the wall for months trying to think of a unique(ish) theme.

I feel like every theme and its permutations have been done to death. What was the last really strong, original theme you've seen? IMO, BioShock was the last one, nothing else since then has stood out to me (aside from that niche beksinski themed game).

It seems one of the major challenges of visual design is simply finding a concept to move on. I struggle to think of anything that isn't derivative of tech panels or bricks. 

Hah, this could even work with Hexen/Daikatana textures. 

"Temple", maybe. "Egyptian Temple"? No way.

Too restrictive of style.

Of course, one could simply place a single obelisk shaped pillar or ankh texture somewhere and say, "There you go. Got that Egyptian part covered." 

Purple Theme. Or Green. Or Green and Purple.

You know, not just the done to death colors like brown, blue, basetan, terracotta, metlbluegray, etc.

|| (this means OR)

Perhaps maybe a Liquids Jam. At least 50% of the map must be underwater (either 50% of gameplay time or 50% by volume).

Topsy-Turvy Jam. Whatever theme/location you want but it must have some or all of it upside-down, sideways, or otherwise topsy-turvy curvy angled twisted. 

brush theme. Maps must be build out of brushes to qualify. 

Must include spikes. Use nailguns. Can use Spiked Quakespasm features. Evil mood recommended. 

Don't be too restrictive.

Temple etc etc hasn't been done much and it's a real strong style - or genre of styles. 

Like Warhammer 40K

Spires and gothic arches in a dark future techy setting 

Well, that's a good reason for being non-specific. If you want to make your temple jam map in a techno Gothic style, then cool.

However, somebody that doesn't like that style could make their map in an Egyptian style. Or as sunken, medieval ruins, or whatever.

The more words it takes to define the theme, the fewer maps there will be. That's what I think anyway.
