I remember beating Super Mario World the first time. It was the first game I ever completed at the time, and I was so excited that I finally beat Bowser.
Then I got the message saying Mario's adventure is over. I don't know why, but that just made me feel empty inside. It's actually over?
Then the credits started rolling by and showing the enemies encountered during the game. Each enemy I saw back memories of all the good and bad times I had. Memories of staying up late trying to beat that castles, getting pissed of at those stupid sleepy fish, having fun flying with the cape. All of these moments have come to an end.... the adventure is over. I guess I learned that everything must come to an end, no matter how good it is. You work so hard at finishing a game, and you don't realize how much fun you had until you completed it. And then you are just sad that its over.
Even to this day, the credits song makes me tear up a little.
