From 1983 to 1993, Enix published games for Japanese home computers including the NEC PC-8801, MSX, Sharp X68000, and FM-7. Beginning on the Famicom, Enix published the very successful Dragon Quest series, which, after the formation of Square Enix, had already sold over 35 million copies worldwide. Although the first few titles were developed by Chunsoft, other companies would also develop main installments, spin-offs, and remakes for the series including Heartbeat, ArtePiazza, and TOSE. The Dragon Quest franchise would carry over as one of Square Enix's most important assets. Other notable franchises published by Enix include the acclaimed Star Ocean and Valkyrie Profile series by tri-Ace, both of which would also continue with Square Enix. The company Quintet developed several role-playing games for Enix such as ActRaiser, Robotrek, Soul Blazer, Illusion of Gaia, and Terranigma for the Super NES.
