Era SMP is a geopolitical Minecraft server that tries to feel more like a living world. It uses a bunch of plugins so players can keep pushing forward without needing staff to run everything.
I saw tech style progress with things like electricity and machinery plus bigger enchantment caps. There are also moveable vehicles and a raised world height so builds can get wild.
It also has a live map and a lot of extra features from its plugin setup. Most of the time it sounds like you will have more than one project to work on which keeps it from getting boring.
