By far the most three under played consoles I own are my NES, SNES, and Genesis, especially the NES. Sadly, out of convenience I typically bust out the emulators when I feel like playing any of these three consoles and with the exception of the SNES, none of them are currently hooked up due to space limitations. The NES is probably my least favorite console I feel is worth owning, but I still have a soft spot for it. I plan on getting flash carts for each of these system soon which will probably increase the amount I play games on them.
