I think you've hit on a lot of good reasons that resonate with me in a fairly short comment; well done there. One point I'd elucidate on a bit:
> A lot of times you're just chasing nostalgia from that one really good game you've played. Hoping to recapture the same feeling.
I also think back to the 90's - the 8-bit NES was still kicking just about to be replaced by the SNES and by the close of the decade we had the Dreamcast and the N64 was already showing its age; it was a really incredible time of advancement (and I don't think that's all nostalgia from me as a kid at that time). That continued somewhat into the 00's, but really felt like it petered out since. I remember the sense of wonder at what could come next, and I just don't have that anymore.
