My FIRST gaming experience? Hmm...We could go back to the Hand-held "Electronic Baseball" thing I had, which featured a baseball diamond and a bunch of flashing lights. We could talk about this game console that had two knobs on it, and three built in games ("Pong", "Tennis" and "Handball), all of which featured white dots bouncing around the TV screen. Then we moved up to the Atari 2600 game console (how many hours did I kill with "Night Driver"? That was soon followed by the Atari 5200. When "Pitfall" came out, it was like "WOW! What a graphics breakthrough!" Of course, "Pitfall" would now look like "Pong" compared to today's games....
My first PC game? I think it was the first version of Rollercoaster Tycoon that I tried to play on our first computer that we bought in 1999. I don't think it played that well. The PC wasn't a gaming system.
