Vintage games.  

>>Perhaps Atari or Nintendo...
>>Perhaps Atari or Nintendo 8-bit. There's something so satisfying about the blockiness of the graphics; something that fancy 3-d games don't have.
Yeah. I think it's called "nostalgia".
>>Any resources out there?
I recall seeing a documentary on the history of videogames, which I believe was "In The Game", originally shown on CNBC.
There's also this thing, where they're interviewing Nolan Bushnell among others, but I'm not sure if this the same one:

'The A-Z of Cool Computer Games' by Jack Railton is pretty good

More than nostalgia
An appreciation of vintage games shouldn't be dismissed as mere nostalgia. 8-bit graphics and music had by necessity to be simple (which I consider a virtue) yet creative. The music alone was elemental electronic tones, yet had to play perpetually in a game's background to set a mood without annoying the listener.
I asked my boyfriend what his favorite 8-bit theme music is (he's obsessive about design and music) and he replied immediately, "Metroid, Kraid's level". He describes it as haunting, capturing the sense of being isolated in space.
The link below is to that theme music.
And a good read is David Sheff's 'Game Over: How Nintendo Conquered The World.'

I just remembered that Cory Arcangel has been making some neat nintendo 8-bit music. he's on Beige Records with some other like-minded musicians:
