I have a son who will be 4 yrs in November & he is just now starting to play with his toys. He would never play with his toys no matter what I did. I would play with his toys with him and he would just walk away. He mostly wanted to play outside. Luckily we live near a park so we spent a lot of time there... or we would go outside and play with chalk or he'd ride his bike. The good thing was for his 3rd b-day I didn't have to buy any expensive toys for him (being a single mom I didn't have a lot of money to spend) I bought him a few small cheaper toys from Wal-Mart and some books (short ones) for me to read to him. He loved the books! (I'm just throwing out a few cheap present idesas): He liked getting a pack of bubbles (I know it seems like a weird present but he never played with his toys. If you need any other ideas or just want to talk my email is: ____@____.com.
I hope I helped a little :)
