I'm only 20 years old and the 2600 is the system I have the most games for not to mention my interest in the 8-bit computers, but it's hard to find locally. The 5200 is probably what got me started in collecting in general when I got a lot of 5200 stuff back when I was helping someone move. I will say I probably enjoy games on the Coleco Vision a bit more though, but many people now just don't see the magic games from that time period had. Damn kids just care about their halo/call of duty. They just can't have any independent imagination! As far as this Air-Raid cart goes it'd be interesting to find out the legitimacy of it, but it is quite annoying how video game news sites are picking up on these rarities now and artificially inflating the price.
I believe former DP founder Kevin Oleniacz was the first person to make mention of this game having seen a box for this game back in the day. This was long before a loose cart was accounted for. There have been other rumors of boxes seen and collectors having them but I believe he was the first to claim to have seen one. Significant because at that time I wasn't aware of any loose carts in collectors hands.
