Yes, this is VGMaps, not "VGAllGraphicalAssets".
Of course it's up to the mapper how to handle them if at all, but I wouldn't be opposed to including titles and cut scenes and anything else as long as they are neatly arranged and part of an image that is still mostly a map. Like opening sequence shots with the map of the first stage/area, that kind of thing. Though it could be considered spoileriffic to include end stuff with the last stage/area... hmmm. In any case, just like the maps themselves, anything else added should all be kept as neat and simple as possible.
I only mapped the first couple areas of Totally Rad (NES), but I always felt that if I were to redo them or request that someone do them, that the cut scenes could be included in the maps, since the '80s/'90s surfer slang is amusing to me. But as with any game I would be quite pleased with just the maps, as that is the point.
