> video game systems that used interlacing, like the n64, playstation, and up until the hdmi era, did not usually do this afaik, opting to instead drop the frame rate to 30fps with 2 fields per frame, so they really were in many ways the worst of all worlds.

480i Nintendo consoles (N64, GCN, WII) all had many 60FPS games. The 30FPS limit was almost always because of the relatively underpowered hardware. Some N64 games even ran at 20FPS!
