No one outgrows the joys of playing with toys. People sometimes play with toys because they are amusing and fun. Toys are usually simple, but there are hard ones, where you have to use your mind. These kinds of toys can be fun because they are challenging. Another reason people play with toys, is so that they can remember their childhood. A favorite toy can be passed from grand-parent, to parent, to child.

Sentence two- 'hard ones'- it sounds funy to me- I'd extend it to explain which ones you mean. I assume you mean games that require thought, so maybe an example would help.
Sentence three- excess punctuation.
