systems and has taken early legal actions to shut down such projects. To help support older games and console transitions, manufacturers started to support backward compatibility on consoles in the same family. Sony was the first to do this on a home console with the PlayStation 2 which was able to play original PlayStation content, and subsequently became a sought-after feature across many consoles that followed. Backward compatibility functionality has included direct support for previous console games on the newer consoles such as within the Xbox console family, the distribution of emulated games such as Nintendo's Virtual Console, or using cloud gaming services for these older games as with the PlayStation Now service. Market Distribution Consoles may be shipped in a variety of configurations, but typically will include one base configuration that include the console, one controller, and sometimes a pack-in game. Manufacturers may offer alternate stock keeping unit (SKUs) options that include additional controllers and accessories or different pack-in games. Special console editions may feature unique cases or faceplates with art dedicated to a specific video game or series and are bundled with that game as a special incentive for its fans. Pack-in games are typically first-party games, often featuring the console's primary mascot characters. The more recent console generations have also seen multiple versions of the same base console system either offered at launch or presented as a mid-generation refresh. In some cases, these simply replace some parts of the hardware with cheaper or more efficient parts, or otherwise streamline the console's design for production going forward; the PlayStation 3 underwent several such hardware refreshes during its lifetime due to technological improvements such as significant reduction of the process node size for the CPU and GPU. In these cases, the hardware revision model will be marked on packaging so that consumers can verify which version they are acquiring. In other cases, the hardware changes create multiple lines within the same console family. The base console unit in all revisions share fundamental hardware, but options like internal storage space and RAM size may be different. Those systems with more storage and RAM would be marked as a higher performance variant available at a higher cost, while the original unit would remain as a budget option. For example, within the Xbox One family, Microsoft released the mid-generation Xbox One X as a higher performance console, the Xbox One S as
