Best Open Source and Free games and tools for Linux

I was quite inspired with a series of posts on opensource.com that listed five open source games on GNU/Linux systems, in six different genres.

The links to these articles are:

• 5 open source strategy and simulation games for Linux -> https://opensource.com/article/18/8/strategy-simulation-games-linux
• 5 open source role-playing games for Linux -> https://opensource.com/article/18/8/role-playing-games-linux
• 5 open source racing and flying games for Linux -> https://opensource.com/article/18/7/racing-flying-games-linux
• 5 open source puzzle games for Linux -> https://opensource.com/article/18/6/puzzle-games-linux
• 5 open source card and board games for Linux -> https://opensource.com/article/18/3/card-board-games-linux
• 5 arcade-style games for Linux -> https://opensource.com/article/18/1/arcade-games-linux

While these articles are quite good, but they are also very limiting. These articles mention only those game that are fully open source, i.e., the games that have their source code and all assets freely distributed. Also, these articles cover only those games that the author knows or are very popular in the community.

While I am a GNU/Linux, i.e., Peppermint OS, user myself, I am not so strict in my preference of the tools that I use. I am a GOG and Steam user and my games library in these two together has swelled to more than 100 games (This is mostly because of the excellent sales on these two sites and the bundles through the Humble Bundle site)

In the coming articles in this blog I would jot down the many games and tools that can be freely used on GNU/Linux systems. Also, I won't be strict in following genres and would list a few games/tools in each post.
