I used to have Atari 2600 with all factory games and Colecovision with all factory games. But there were a lot of 3rd party games that were not always available. Especially as TV systems have different frequencies and formats. (PAL, Secam, NTSC, etc). So the offer in other parts of the World (US, Japan) was bigger.
I also had a Vectrex, Philips CDi and one of the first Pong for TV devices. Still have that one somewhere.
But these collections on those pics are just insane. You need a complete room for storage alone.
I'm working on my game room, but that is meant to actually PLAY games and not watch them rest on shelves.
You must be a real die-hard fan or über-collecor, to assemble a collection like that.
What i do know about early video games, is that they involved you, even if the graphics were basic and the posibilities limited.
A lot of modern games, even with all eyecandy and effects, can not even come close to those. Addictive and fun.
That's why they keep appealing to the older generation of gamers and also the curious young ones.
Right now we can get emulators for about every possible system around. I like MAME for example. And with MAME you can play the good old Arcade classics, that were the base for a lot of the TV Consoles games from the past. And the arcade games are 10x better in quality than those old consoles.
I still play those MAME games on occasion. And most ROM's are available somewhere.
Same goes for VpinMame where you can emulate the pinball machines. Still better than most pinbal games i have bought on Steam.
Some of my own collection has magically dissappeared, but i still have some golden oldies laying around.
