The only other full-length Stoppard play that I've seen is Arcadia. I don't recall any outstanding language tricks, although I do remember some plays on words. What really struck me was the parallel, interwoven tales of people living in two different centuries (1800s and "present day"), but in the same physical setting. The present day characters at times misinterpreted history due to unrecorded details in the 1800s characters' lives, yet they had knowledge of events still in the future for the 1800s characters, leading to an interesting mix of humor and foreshadowing. I loved seeing the two perspectives in time, and I found the story heartbreakingly beautiful.
