Notch should add...

Minecraft.

Everyone knows it, everyone loves it.


But Notch / Jeb should add a few things to make Minecraft a better Game.
Here are some Examples:

1. Friendlist
2. More Mobs
3. More Ores
4. Quests (NPCs)

Not enough? See all things, Jeb should add on my Blog at Planetminecraft.com
