For a while, I've been looking for a seed that contains everything I need within a close proximity. That means I need a stronghold, a nether fortress, a village (with decent crops), and anything else within 500 blocks from spawn. Mostly, I'm just looking for a stronghold village with carrots/potatoes and a nether fortress nearby, so if anyone finds anything like that, please let me know! I've found a couple of seeds, but either the stronghold has no portal or the fortress has no nether-wart or the seed is for a different version of Minecraft. It would be especially great if we could find seeds with a whole bunch of things near each other: stronghold village next to a desert temple on top of a mineshaft which connects into multiple dungeons and so on and so forth. If anyone has found anything like that, please put that in this thread! If I find anything, I'll also update this.
This isn't what I was looking for, but it's a really cool seed! On my way to the stronghold (coordinates 192, ??? 1600), I passed by at least 6 villages, at least 3 of which had blacksmiths, and 1 which was a zombie village! Also, I spawned near a small ravine with visible diamonds at the bottom, and passed by at least 2 other ravines. So far, I only found 1 desert temple on this route. I think there's so much more to explore, so I figured I'd put this here if anyone wants to check it out!
I found this seed while experimenting with a new texture pack, and it ended up being almost perfect! You spawn in between a plains and desert biome, but if you keep walking around, there's a savanna biome with a double village (one of which has a blacksmith). One of these is also a stronghold village, with an enderportal. Back at the villages, if you put down a nether portal, you will spawn right in a nether fortress with netherwart! I don't think it matters exactly where you put it, but just somewhere within the village and you'll spawn by a fortress. Now, all of this is really cool, but it gets better. Underneath the village, there's also an abandoned mineshaft! I found it while exploring a ravine a couple of blocks away. I think this seed would be really good for completing the game quickly, as there's a stronghold village and a nether fortress near spawn.
