It could have been worse, but I wasn't particularly impressed. This guy is mostly relying on western media reports and not digging into the Japanese materials at all.
I could nitpick through the sketchy details, but I won't for now. Anyway, what disappoints me is that the full story of the PC-FX is so much bigger than this. You have to start with the PC Engine, and realize that even though it may have done well in '88 and '89, they never had more than maybe 20% of the total Japanese market share. When the Super Famicom came out in late 1990, it spelled doom for the system, and NEC/Hudson shifted their focus to CD-ROM games. In turn, their efforts to set the CD-ROM system apart with unique software caused a shift in the kinds of games that came out on the system. By mid-1993, they were really focusing on developing anime-style digital comics and RPGs, similar to what existed on Japanese PCs but with all the trimmings that a CD could provide. It's from this background that they chose to design the PC-FX the way they did.
