There are also some tradeoffs with the Atari 5200, but that hardware is weird, and rarely sees its full potential, most games on it look like ass but every now and then you get something impressive. 5200 has a much bigger Master colour pallette than both NES, and Master System, but its on-screen
limitation is really crappy without tricks, with
tricks I think it could probably out-do the NES in straight on-screen colour counts though, but only if the graphics style of the game fitted the tricks, there was a very talented developer, and they spent a lot of time optimising everything. Outside of that though the native resolution, and sprites on 5200 are quite crappy in comparison to NES, I believe the soundchip holds up respectably though (unlike the 7800 soundchip, funnily enough).
