When you first launched Minetest, didn't you think it was just Minecraft? Actually not. Although their interface, style, and gameplay are almost the same, Minetest is essentially a free, open-source and cross-platform voxel game engine (written in C++ and Lua, using the Irrlicht Engine). It was created by Perttu Ahola and first released in 2010, and is now developed by a team of volunteers, with significant contributions from the community. It's available for Linux-based systems, FreeBSD, Windows, Mac, and Android platforms, and provides an API for users to create their own games and mods written in Lua.

First of all, not all of the wonderful music you heard can be bought or downloaded from somewhere. Then, if I said the background music of a lot of games (especially the ones categorized in adventure type) are really awesome, I think most game players will agree. So how to get them out from games for direct play or collection? This case, third-party tools are almost always required, and of which, a game audio extractor is preferred. As for recording game music, that's just a remedy way.

On the face of CastleMiner Z, I guess most players are likely to think it as a MOD of MineCraft. In fact, they just look alike. CastleMiner Z is an action-adventure game with very high playability. It was developed by DigitalDNA Games, based on sandbox gameplay, and belongs to the survival type of zombie horror game.
