Star Force

In Japan, Game Machine listed Star Force as the fourteenth most successful table arcade unit of November 1984. Reviewing the Arcade Archives release on the Nintendo Switch, Dave Frear of Nintendo Life gave the game a 5/10 score, noting it to be mediocre and unoriginal for its time.

Star Force was ported and published in 1985 by Hudson Soft to both the MSX home computer and the Family Computer (Famicom) in Japan. Sales of the game were promoted through the first nationwide video game competition to be called "a caravan", although it was not the first event of its kind organized by Hudson (they had previously promoted Lode Runner with a similar event). The North American and European versions for the Nintendo Entertainment System (NES) were published two years later, in 1987, with significant revisions, and with Tecmo credited rather than Hudson on the title screen and box art. According to Keiji Yamagishi, the NES version was created separately at Tecmo and is distinct from the port released for the Famicom by Hudson. Although the NES version is immediately recognizable as having a great deal in common with the Hudson version released in Japan, there are significant alterations to the graphics, music, and controls and gameplay. Several bugs in gameplay were fixed (debatably making the NES version more difficult) that allow the player (in the Japanese version) to prevent new enemies from appearing ("spawning") by not shooting the enemies already on screen. Star Force was also ported to the SG-1000 by Sega, and X68000 by Dempa Shimbunsha. In 1995, along with two other NES shooters, the Famicom version of Star Force was remade by Hudson Soft with minimal upgrades for the Super Famicom as part of the Japan-only release of the Caravan Shooting Collection. The Famicom version was also included in Hudson's compilation of NES shooters in 2006 in Hudson Best Collection Vol. 5. The original arcade version was later added to the compilation titled Tecmo Classic Arcade, which was released for the Xbox. In 2009, the arcade version was made available for download on the Wii's Virtual Console for 500 Wii Points as one of the four initial offerings for the "Virtual Console Arcade" category of the Wii Shop Channel (the other three being Gaplus, Mappy, and The Tower of Druaga from Namco). In 1986, Hudson Soft released the shoot 'em up game Star Soldier, which is considered a spiritual successor to Star Force. The game spawned numerous sequels. Hamster Corporation released the game as part of their Arcade Archives series for the PlayStation 4 in 2015 and Nintendo Switch in 2018.
