Minecraft is one of the most popular games between the young and the not so young. Despite being a game with not very good graphics, users end up sticking to their peculiar way of creating alternative worlds. Currently this game has an official adaptation to GNU / Linux thanks to Java technology but this type of application is not very light and more still not free as it has a price that although not as high as that of some video games, it is considerable.
That is why we have selected three alternatives to Minecraft which are completely free and just as functional as the original Minecraft. Also in some cases these games have an interface or some feature that exceeds the original at least according to its users.
Minetest is one of the most popular games and has originated more versions. It is also the most developed game, already having a version for Wily Werewolf. In addition to being free, it is also Open Source and has an own repository which we can use to install on our Ubuntu. Of the three options, Minetest is the most similar option to Minecraft, although with some changes in some terms or tools for legal reasons.
Terasology is one of the alternatives that has substantially improved Minecraft. As can be seen in the images, Terasology has greatly improved the graphics by differentiating elements such as water, sand, etc … However unlike other alternatives, Tesarology cannot work on low-resource computersRather, you need a slightly more powerful computer with at least a decent graphics card. It is rare to find games with high requirements but the results are worth it. Also, like Minetest, it is free and open source.
Freeminer is based on Minetest. Unlike other Minecraft alternatives, your goal is to be the most fun possible so it is one of the versions with more scenarios, tools and users that exists. It is free as Minetest and open source, but unlike Minestest, its installation is not through a repository but through a package with generic files for all GNU / Linux distributions.
Personally I do not understand the fun in this game but it is good to get free alternatives to such a popular game, also with many tools and scenarios that in some cases can surpass the original video game. The decision is now yours and you just have to choose. Below are the links to the alternative download websites.
