Sonic PC Collection is a PC CD-ROM compilation that bundles four previous Sonic releases into a single package. It was released in 2009, exclusively in Europe, Australia and New Zealand (PAL) regions. In 2011 Australia also received a 20th anniversary special edition, called the Sonic Anniversary PC Pack, which included a mouse and mousemat.
Of the included releases, two contain emulated versions of older games, making for a total of 29 games. The package comprises 6 CD-ROMs (games that were originally released on two discs (Sonic Adventure DX and Sonic Heroes) were not repackaged onto DVDs).
