Oh it did huh? Lucky, as I submitted, everything went down, so on the redirect it pulled the "maintenance" screen, so I didn't expect it to get the data, Nice, but yeah I'll reply here from now on, because the forums are more public, bumping this post is good, and honestly, I stop by the forum maybe once every 3 months, so I take my time when I do . And yeah the flagging deal has been an idea from long ago, back in the day the sky limit was so short, and everyone wanted a better system, although as we all know, mojang has yet to actually put effort into much after release, I mean it takes them months to implement things in, that it takes modders (aka amateur coders), that code in their spare time, to actually implement in 3 hours. I mean, how long did it take them to tweak the terrain gen to support 256? months of work on end, it took a few amateur coders in 2 weeks to do the same but doubled. The base game of minecraft was genius inside itself, but the lack of work they are putting in now is neglectful of a powerful creative engine. But back on topic, the code for this actually wouldn't be spectacular at all, I mean, if you take a look at terrain gen code, and chunk code, it isn't very complex, the only thing I see posing a major problem is tweaking the size to be completely editable, maybe hooking in with plugins like, let's say... Optifine, and it's ability to add chunks to render, in and out, from extreme to tiny, in a bar, more or less to help those who need to balance the amount of chunks rendered themselves, aswell as possibly adding a dynamic way of mob spawning, because vertically this would influence cave mobs heavily, it would take much longer to have anything to attack due to the unusual spawning, essentially making mining easier than it already is. I think a proximity/vision spawning system could be put in place. By that I mean as close as possible, that can't be seen directly by players (unless above sea level). Aswell as I think there should be more structures generated into the world, like skylands, sky temples, more ruins, sky NPC villages, underwater relics, underwater ruins, more dungeon types, etc.
