long story short........
Let me know what you all think :-)
To be honest I'd have to break this down in full to address some statements you made if I want to adress everything, but I wont, so here is the basic reply:
1. If you keep running into a younger generation that is constantly hanging out at the retro store, but just so happens to be individuals whom are not actually into playing retro games, then what you have probably run into are actually hipsters or posers, not real gamers. There is a difference, and this has been addressed here before multiple times. If this really concerns you, try checking the age of people on the Neo forums, Sega-16, and other sites. You will find there are actually quite a few teenagers on each of these forums.
2. In my own experience, my son and daughter both love playing the older stuff too now and then, and my son keeps a Snes and N64 in his room with all his other game systems. In fact, a couple weeks ago my son came in here and beat Splatterhouse for Pce on his 2nd try and had a blast doing it. Also, a two year old child's lack of want for 8-bit, 16-bit, and 32-bit games should not even be considered or factored into to any conversation like this. The two year old cant read or write, let alone carry on a coherent conversation. Would you let your two year old pick out your dinner? No. Would you let them pick out a movie to watch on movie nite with the wife? No.
Two year old kids have no reference level, so you cant even begin to base the future outcome or demand of classic gaming on a kid that young. They are not even remotely old enough to form educated or responsible opinions or develop personal taste or preferences yet. If you need that put into perspective a tad better, here watch this video:
Now, after you are done watching it, swap the cat for the 2 year old. Get the point? Stop worrying about a 2 year old reaction to old games. For that matter, stop worrying about what is going to happen 20-30 years from now with these games. Odds are you will be dead, or too old to care by then anyway. Enjoy the here and now, that is what matters.
