True. But Gary comes up with several interesting games, including a previously unpublished one by Roald Berthelsen, who has been playing the BDG longer (and better) than I have, and that's quite a long time.
How long? Here's one of Berthelsen's BDGs published by Nick Kampars in the second issue (March 1962) of his Blackmar-Diemer Gambit insert in Chess World.
