You know you're an old gamer when...
There were no DVD's (you went to movies at the theatre, and when they were gone, they were gone unless/until - years later - they might have shown up on TV).
There were no cell phones (and you hadn't yet been suckered into believing you needed one, let alone a new one every year).
There were no music CD's, music was on vinyl records (look it up).
There was still no Internet to speak of (it was originally a way to keep military and university networks going when the Soviet Union took out most of the cities in North America; once that threat was gone, it became viable as a product for home use).
The Soviet Union fell, and you realized the world would probably not be destroyed by a nuclear war after all.
There were no VHS recorders (see DVDs).
There were no home computers of ANY kind (you read books, or went to movies, or played board games with people on your kitchen table - and they were called "friends" then, not "RL friends".
There was no Cable TV, and thus, among other things, no 3-minute movies with rock bands, boy bands, girl bands, or thugs trying to be actors.
Having a digital watch was cool, but they were VERY expensive (I knew a guy who bought one for over $250, and it just told the time and had an alarm function).
You read Lord of the Rings, and Dune, and a thousand other books, just for the love of reading them, not because you'd already seen the movie. You also did not NOT read a book "because you'd already seen the movie".
You watched Neil Armstrong (live) stepping down onto the surface of the moon and it was the most amazing thing you'd ever (or since) seen. Then later on that year, you started high school.
You moved to Toronto from Northern Ontario, and found out about this amazing new science fiction show called "Star Trek", only to discover that it had just been cancelled.
You had a black and white television until your mom won a colour TV in a contest. It (like all TV's at the time) had a dial that you physically turned (from 2 - 13, if memory serves) because there were no remote controls.
"You remember when comic books were $0.35" - Try 12cents for the regular ones, and 25% for the "80-page GIANT!", and you could buy them at the corner store instead of having to get driven to a comic collector store.
You remember your mom crying but didn't understand who "President Kennedy" was (I was 8 years old, and Canadian, so he wasn't our president, but I still remember that vividly).
You can't help but grin when you get asked "how old ru?", because you know you're almost certainly older than the questioner's parents, and have lived through all of the years of the above, but still enjoy the idea of flying around in a superhero game, just for it's own sake.
