I recently saw Final Fantasy VII, on the Playstation, played on a modern largish-screen LCD HD TV. It was... not kind. Text in particular was barely readable in a divided-into-scanlines way, console games of the era relied a little on the blur inherent in lower resolution screens. Computer monitors have traditionally been a bit sharper than contemporary TVs (even now, though the gap is narrower), but I can imagine some things still not coming out of the warts and all treatment well.
