After the original release on the Amiga and Macintosh, then the Commodore 64 and IBM PC, it was ported to several other computer platforms and video game consoles, specifically the Atari ST, Acorn Archimedes, Amstrad CPC, Sinclair ZX Spectrum, BBC Micro, Acorn Electron, Super Nintendo Entertainment System (which was later released on Virtual Console), EPOC32, mobile phone, Internet, Windows, FM-Towns, OLPC XO-1 and NeWS HyperLook on Sun Unix. The game is available as a multiplayer version for X11 Tcl/Tk on various Unix, Linux, DESQview and OS/2 operating systems. Certain versions have been re-released with various add-ons, including extra scenarios. Two 'Graphics Sets' packs were released, 3 sets in each, which change the graphics and messages in the game, for both DOS and Windows versions. An additional extra add on, included with the Windows version of "SimCity Classic" was the Terrain Editor - a 'level editor', or city map creator. The Terrain Editor is a simple tool that allows the user to create maps with forest, land, and water portions. "SimCity Classic" was re-released in 1993 as part of the "SimClassics Volume 1" compilation alongside "SimAnt" and "SimLife" for PC, Mac and Amiga.
