Depends on your dog for sure, some dogs love to wrestle, mine included. Others like to run and chase each other. This is definately an invite to play. If you don't want to play fine, then don't. Or wait and you initiate the play. With my dog, I'll do both, if I'm just sitting there doing nothing and she brings me a toy, sometimes I'll play but if I ignore her for a bit, she goes and entertains herself. She's always willing for a good game of tug or a bit of a wrestle.
