Yes, I had "imaginative play."
No, I have no idea how "good" I was at it. Most of my time was spend arranging my action figures (mostly figures of animals) into "societies." I would build houses, lakes, invent the forms of government, ect. Sometimes I got around to actually acting-out scenarios, but they were mostly based on junk I saw on TV, or I would invent a script I liked, and then I would keep repeating it.
I preferred not to play with other children because they screwed everything up.
As for role-playing, I always pretended to be an animal. My mother joked that I didn't learn how to walk on two feet until I was ten since I was eternally charging around the house on all fours.
ANYWAY......I told this to my psychologist, but he insisted that the DSM-IV criteria doesn't require a lack of "pretend play" to be DXed with Aspergers. It's also worth noting that I have many ADHD-PI traits, and they might be altering the AS traits a bit (just a theory). And the DSM-V criteria specifies that it's SOCIAL IMAGINATION that matters, not whether or not yo played in your room, by yourself, with your "My Little Ponies" figurines.
Is that "normal?" I don't know. I didn't play with other children enough to know what "normal" is.
