Minecraft mods owners more control over their "Minecraft" environments. With the release of the alpha version, the first client-side mods began to appear; these added relatively simple things, like other textures or amendments to the in-game compass. Towards the end of 2010, new mods were released which featured more content than previous ones. "Minecraft" was now preparing to move into its beta development phase, and popular mods such as "IndustrialCraft", "Railcraft" and "BuildCraft" were first released to the public. As opposed to their predecessors, these mods had the potential to change the entire game instead of simply tweaking minor aspects of it.
