Speaking of strictly my own stuff I'd need to contact original owners before posting anything that's not my own. I've go so much stuff from people that's simply incredible and it's a shame that it won't see completion.
A good example is the portal level that Bob exported. It's stunningly good and if you turn off the hud you would be hard pressed to know which game you fired up. I've also got multiple levels exported from other different games that worked as a proof of concept but they need attention from people who would lend some of their expertise and a bit of time. There's a bunch of guys (you know who you are) that mess around and do some fucking neat stuff but it never gets moved beyond "Wow, that's pretty cool." Rune, Minecraft, Left4Dead, Postal2, Killing Floor, Doom...I have maps or parts from those and that's just what I can remember without going to look.
Anyway if I have these then you guys too are bound to have maps that have a lot of work in them but aren't ever going to get done. Why not offer them up and let's get a completion team together? Nels can enjoy a well-pathed map because he did it, Barbie endorses that all the triggers and map flow are correct, our resident map contest big hitters can tighten up the texture choices and do some interior decorating, etc. It may not be the exact map you started to make but this way it gets done, it's engine correct, AND it gets released.
It might be nice if the community had central focus projects to work on that didn't require much from any single person and was open to those that had both the skills and the time.
"You damn kids, back in my time we made the items, maps and games ourselves with an unwieldy engine using counter-intuitive crash-prone tools and we liked it so much we built communities around this which nowadays look like cults because they're quasi-parallel societies based on the same old games." -Hellkeeper
