"one trick pony" is somewhat older lingo than electronic games i think

[Pete_D]

Online Etymology Dictionary claims: "The figurative one-trick pony is 1897, American English, in reference to circus acts."

Could be. I admit I heard it first in videogames but I am not an authoritative source.

yeah the term is older than gaming, but I brought it up in reference to DoTA.
