I was going to add the part about empathy... I think we questioned ASD a number of times with DS6, but if anything he's OVER empathetic/sympathetic. The thing about not playing with toys gets me because DS6 never played with age appropriate toys (which actually made it difficult for me to buy for DD4 because she is at her age level). It's obvious (to me) that a gifted child wouldn't play with age appropriate toys, as they are "boring" so to speak.

Good luck in figuring it all out!
