When looking at a generation as early as 8-bit, people interested in (arcade) usually just want something in the same general spirit as the original or want to see how a game was handled on the inferior hardware. So if strict rules are used, then a second list of 'based on' titles should also be kept, as it will likely be at least as useful to most people.
