I think a good action game that is simple and of Japanese origin is Bubble Bobble (try NES) as it was originaly intended to bring couples closer together through cooperative gameplay. you can always go with the obvious mario games. also, Guardian Legend (I'm still on the nes, here...) is a great and challenging action adventure game with good graphics and. I understand having an old PC as mine is like a 1999 dell. I reccomend getting a USB Dpad or two, as 2 player games are no fun when you have to share a keyboard. If she likes rpg's but not so much the traditional Knights and wizzards kind, you can get Earthbound (Nes or SNES...) because they are cute, have an interesting story, and are not very difficult. also, hope I helped ya out!
