Man, I'm going to really age myself here, but it was Pong, ha ha. I think that might have been the first video game made.
I had Atari, Nintendo, and stuff, with all the oldies. Asteroids anyone? How about Space Invaders? You can laugh. I'm okay with that. Even early games were a lot of fun. I also got to experience arcade gaming, which was definitely cool. The local arcade was the best hangout.
When Play Station came out, I realized we had come a long way. PC gaming is my thing though. I was an avid World of Warcraft player for years.
