Sega's CD-ROM attachment didn't do much better, despite a global launch and the power of the Sega brand internationally. It was more powerful than NEC's system but the games were still largely unimpressive, offering an almost identical standard of gameplay as standard Mega Drive / Genesis titles. Attempts were made to create a unified platform in the shape of the JVC Wondermega and Sega Multi-Mega / CDX, but neither caught on. Alongside these two high-profile flops there were other disasters, such as the Commodore CDTV and Philips CDi. Simply put, combining 8 and 16-bit hardware with CD-ROM drives didn't seem to make commercial sense in the early '90s, despite the public's constant demand for new and interesting cutting-edge tech. CD tech arguably didn't come into its own until the 32-bit generation; everything prior to that was a false start.
