I never lost any of mine either, maybe after a few years I did. I was 3 or 4 when I got a Shogun Warrior. It had about thirty missles in it. When I got rid of it, ten years later I had lost 2 of em. I kept my stuff in great shape. All my vintage stuff has play wear on it. I lost alot of my vintage collection in moving but thats about it. I never lost a sliding saber on my vintage either. Kids (to me) seem alot more spoiled today then we did. They seem to have an "I dont care" attitude. That combined with the way toys are made, dont mix. Plus combined with the prices of them really dont mix. I would rather loose my wallet than pay 40-60 dollars for a toy that is gonna be broken in the matter of a week.
I played rough with my toys. I would slam them against walls and everything. They were made like football players. Nowadays it is like roughing the kicker.
