WinterSMP

The WinterSMP modpack desires to make exploration in Minecraft more interesting and improve upon Minecraft's often predictable play style. This modpack also tries to stay close to Minecraft's feel and adds mods that would seem like it could be added to the vanilla game. 

A player who uses this modpack would find it hard to get bored due to the countless items and mobs they can discover. 

Lots of Minecraft's structures have also been improved upon and many more have been added, so you won't get bored of finding the same structures over and over again.
