Wine (known recursively as Wine Is Not an Emulator) is an open-source compatibility layer for Unix-like systems (e.g. Linux, BSDs, and Mac OS X) to run programs originally created for Microsoft Windows. Originally created by Alexandre Julliard, it is now sponsored by corporate entity CodeWeavers, who use it as a base to create an enhanced, proprietary version, known as CrossOver.
Wine is especially useful for older Windows games, as compatibility with these is typically higher than if the same game were run on modern Windows versions.
Wine can also run many Windows programs, including emulators. Compatibility may not be perfect however, and there can be various glitches introduced.
With some programs, official Windows DLL files are required. Most of these are available to download via the (usually) included script, winetricks. Compatibility lists for most programs can be found on the AppDB.
Games which use DirectX/Direct3D APIs later than 9.0 are mixed in terms of support, as many DX10/11 games/programs run, however many still simply don't run at all.
On the downside, there are some programs that are simply impossible to run, due to restrictions regarding how Wine works. Programs such as GameGuard and certain other anticheats for games will not run at all, due to it being impossible for Wine to implement kernel-mode drivers. Games such as those by Nexon and other companies that utilize these types of anticheats will only run through a virtual machine (however, sometimes even then, there is no guarantee).
