The NES.
Not just for reviving the console market (and bringing it to Europe btw), but also due to it's controller. Just compare the controllers of Atari 2600 and others of their generation and the NES: D-pad, Start & Select buttons (or something along those lines), AB buttons (which now have become ABXY with a second row of buttons), those have all become standard nowadays, as have holding the controller essentially sideways and not like a remote.
