My personal favorite would have to be the SNES. For its time, it had incredible hardware, augmented in certain games by the inclusion of Super FX chips in the carts, among other chips. It spawned many of the greatest games ever made, namely, Final Fantasy VI, Super Mario World, Mega Man X, and Chrono Trigger, though that list barely scratches the surface of the tip of that iceberg. Homebrew mods are still being developed today. Something I found amusing is that the system was specifically designed so you couldn't balance your drink on it. NES owners would do that, which ended up ruining the console when they spilled.
