True, but there was a huge difference between a good-quality RGB monitor and a consumer TV connected via composite video or RF. Ideally designers would have been using development devices that took that difference into account.

For example, I've heard of artists at Sega drawing on PCs and using custom hardware so they could simultaneously view their work on a real Genesis connected to a typical TV.
