Throughout the years Katamari Damacy and its successors have gone on to be developed for multiple platforms.  A platform is a type of consol on which the game can be played.  The most popular of the consoles the Katamari franchise has appeared on are the Playstation 2, the Playstation 3, the PSP, and the Xbox360.

The PlayStation 2 (often shortened to PS2) is a sixth-generation video game console manufactured by Sony Computer Entertainment. The successor to the PlayStation, and the predecessor to the PlayStation 3, the PlayStation 2 forms part of the PlayStation series of video game consoles. Its development was announced in March 1999 and it was released a year later in Japan.

The PlayStation 3 (officially abbreviated as PS3) is the third home video game console produced by Sony Computer Entertainment, and the successor to the PlayStation 2 as part of the PlayStation series. The PlayStation 3 competes with Microsoft's Xbox 360 and Nintendo's Wii as part of the seventh generation of video game consoles.  The PlayStation 3 was first released on November 11, 2006 in Japan and November 17, 2006 in North America.

The PlayStation Portable (officially abbreviated PSP) is a handheld game console manufactured and marketed by Sony Computer Entertainment. The system was released in Japan on December 12, 2004 and in North America on March 24, 2005.  The PlayStation Portable is the first handheld video game console to use an optical disc format, Universal Media Disc (UMD), as its primary storage medium.  Other distinguishing features of the console include its large viewing screen, multi-media capabilities, and connectivity with the PlayStation 3, other PSPs, and the Internet.

The Xbox 360 is the second video game console produced by Microsoft, and the successor to the Xbox. The Xbox 360 competes with Sony's PlayStation 3 and Nintendo's Wii as part of the seventh generation of video game consoles.  The Xbox 360 was officially unveiled on May 12, 2005. The console sold out completely upon release in all regions except in Japan, and, as of October, 2009, over 34 million units have been sold worldwide. 

The DualShock (Trademarked as DUALSHOCK and occasionally referred to as Dual Shock) is a line of vibration-feedback gamepads (remotes) by Sony for the PlayStation, PlayStation 2, and PlayStation 3 video game consoles. The DualShock was introduced in Japan in late 1997, and launched in America in May 1998, meeting with critical success. First introduced as a secondary peripheral for the original PlayStation, a revised PlayStation version came with the controller and subsequently phased out the digital controller that was originally included with the hardware for insert manually, as well as the Sony Dual Analog Controller.  The vibration feature on this gamepad is especially helpful in the Katamari Franchise because it gives damage warnings while in gameplay
