When we had been inside earlier and they were trying to play with cars together (something DS does EXTENSIVELY and elaborately on a regular basis in his own little world), we ran into problems because he just had a certain way it wanted to be done. He is usually the king of his little vehicle-play world, and the other little girl stared blankly when he started going on about the toy train being a steam engine and needing coal. When they tried to race them, well, let's just say all hell broke loose. He is very particular about how he plays with his cars, and is used to doing it alone and at-will, or with an adult.
This sounds less like a gifted thing and more like a kid who hasn't had to negotiate playing with others much yet.
I don't know, ultramarina, if the child is playing at concepts those children don't get the play could look like that. If the other children are at the push it along and make chug-chug noises while he is at the trains need fuel and stations, and a developing storyline, he is going to look bossy, and the other children are going to be a bit flabergasted. He might not even realise the other children can't play like he can, and think they won't play, something that could be very frustrating and upsetting for him.
