I know it's a little dumb to spawn a new world just before a game update (likely a big one too), because there might be changes to how worlds are generated. But I couldn't help myself this afternoon. Made a bunch of worlds one after the other, in the hopes of finding something new/interesting.
When you can make worlds over and over, it tends to make a person picky. I now will frequently delete a world if I don't see coal within about the first 10 seconds. :lol
Anyway, I ended up finding a keeper.
1) Is this what I think it is, RIGHT at my spawn location?
2) Yes. Yes it is. It seems to be somewhat glitched - it is filled with sand and I was able to dig right to the storage chests. I've left it for now but will eventually build some glass and use it to harvest string. I'm lucky it is a spider dungeon. String is the only non-renewable resource in the game.
3) There are also naturally formed mega-trees right by spawn.
4) Even with the odd dungeon I was still considering deleting the world, but I decided to dig a spiral mine shaft straight down, to see what I could find. I eventually dug into a big cave system, and this was the very first thing I saw:
Talk about luck, right? The cave is HUGE in the way that only other Minecraft players can understand. And I've only found *one* more diamond. Crazy I bumped into three right away, so far up from the bedrock.
The cave is mostly monster-free too. Some skeletons, and that's about it.
...so yeah. I think this world is a keeper. Hopefully Biomes or something else awesome but save-breaking aren't introduced Friday :lol
Edit: Oh yeah it also had papyrus and cactus right by spawn, which also led to my decision to keep this one.
Edit2: given the sand-filled dungeon, supertrees, and suspiciously high-elevation diamonds, I'm think world gen was a little bugged and might have elevated some stuff (or all stuff) ~15-25 blocks, or something.
