Lutris

Lutris is a free and open source game manager for Linux-based operating systems developed and maintained by Mathieu Comandon and the community,[2] listed under the GNU General Public License.[3] Lutris has one-click installation available for games on its website, and also integrates with the Steam website. Installer scripts are available for some difficult to install WINE games including League of Legends. Games purchased through GOG and Humble Bundle can be added through their own runners in Lutris.[4] Games are run using their respective platforms such as Wine, Steam and emulators and they can be launched through the Lutris application.[5] Lutris supports over 20 emulators including DOSbox, ScummVM, Atari 800, Snes9x, Dolphin, PCSX2 and PPSSPP.[6]

As a game manager it can pull games from various services, like Steam for Linux, Steam for Windows, Humble, GoG, and also games installed through Steam running with Wine, native Linux games, browser games, and emulated games and launch them from one place. These different services or sources are called runners and are used to aggregate the games in one place. All the games installed through these sources are listed in user's lutris window, and can be launched, uninstalled, and tweaked from there.

Aside from being a game manager it allows users to install games directly from a huge online library of user contributed scripts. These make installing games on Linux very easy, with a few clicks, especially those using Wine and that need tweaks, registry entries, or specific tools to run correctly. Games can be installed either through the Lutris website or through the app itself. During installation Lutris takes care of all the setup: installing the right Wine version, the right tweaks, creating the folder structure, enabling DXVk, or whatever other tool the game needs to run. This makes Lutris particularly useful for installing Windows games, because there is no need to run the installer through Wine, creating a new prefix, using winetricks to set some things up, or running command lines - all of that is done by Lutris. Some games offer multiple installation options, either to install the game from various sources (like Steam or GoG) or to offer various install scripts that might work better or wore on user's hardware. Lutris displays ratings for these scripts, and some additional instructions one might need that Lutris can't handle itself, like installing dependencies. Lutris allows the user to tweak a lot of settings for each game and runner. While games installed with a Lutris install script won't need these, since they’ll apply them all for the user, games one installs manually or through steam might benefit from a few tweaks. Users can enable or disable DXVK or VKD3D for Direct X Games, enable Feral Gamemode, Esync, or even tell the game to run at a specific resolution or in a virtual desktop. Users can also choose the wine version they’ll use, and download new ones from the Wine runner options.

In 2013, when Steam support was first added to Lutris, OMG! Ubuntu![7] noted that the database of Lutris games had thus far been limited. They also noted that while it was possible to submit installers for the Lutris database, each addition needed to be manually approved by the Lutris development team.
