‘I will add infinite maps’
Notch decides to add infinitely large maps to Minecraft. He admits that technically maps are limited to 324 nonillion blocks large but says that any computer will run out of disk space before approaching that limit:
There’s going to be a LOT of work to be done after this initial release of infinite maps, and that release might be a pretty big step backwards in functionality in some aspects (water might not work at all in it, for example), but I think I can reach this first release pretty fast.
