They said something along the lines of "Dead Fantasy was what put Monty on the map and Tifa was one of the first character he used" or something like that. And Tifa does appear in DF1, though she is the third FF character to enter the battle.

(When they said that DF was Monty's first big thing, all I could think was "what about Haloid")
