Yeah hate to say it but by the time this golden age ends with valve I'll prob either not be gaming as much anyway or to your point have enough that I won't really care about the newer games.
I mean, I'm not even bummed! Life has gotten very busy, but I have about 10 old standbys in multiple genres. When time allows, I can get tons of enjoyment out of them.
I look forward to playing them years into the future and don't feel limited. It's rare that a new game piques my interest and rarer that it hits my "list"
