If word of mouth is null then just about everything everyone says is worthless, including most shit you say. It's easy to use that as a defense, it shows you have nothing to say.
Simply put, the old games do not have better or more gameplay than they do now. The only thing that made older games hard was the fact that alot of games had no kind of save system. You would have to play through levels without dying or you had to start over. If the games saved after each level then the games would be a breeze and you could finish it in one sitting.
You take a kid who is new to games and give him something new, then something old and they like the new stuff. I did this with my cousins on vacation who do not own any games. I had a gamecube at the time and all they wanted to play was Mario Kart DD instead of super mario on the SNES.
