Man, last time I played Minecraft was a server with a whole bunch of mods added.
What mostly made it interesting was a giant amount of food and food crafting added, so I could spend all my time farming and trying to make an endless supply of pizza.
I don't know, maybe someone should make a game with an actual goal of hoarding, it'd probably be a hit.
Still, I have an idea for a construction, it just probably requires way more emerald than is reasonable. I also recall going crazy with trying to make a path so I'd never have to leave a building at night, so me and reasonable don't exactly mix with Minecraft. I might get back into it at some point.
