As I've written about before, sometimes games are indivisible from the experience around which they've been played. Games are a part of who we are when we first experience them. Sometimes, over time, those games change by virtue of the "us" playing them changing.
Sometimes, the same happens via community. Playing a game in its peak audience, with a certain kind of playerbase, creates a different feeling than one during its twilight years, sinking sadly away in population. Games can, in that way, go extinct.
When looking back on what games were, I can't help but miss the idea of what they were to me as well. Sometimes I just want to go back to a home that doesn't exist anymore, and that's a feeling that's hard to shake off.
