No. Othello, a trademarked 20th-century commercialization of the older Reversi, is recorded as a distinct entity alongside it.
Space and Territory Games covers games scored by controlling territory on the board, such as Go, Othello and Reversi. Othello is the trademarked 20th-century commercialization of the 19th-century game Reversi, and both are recorded here as distinct entities under the same family rather than one superseding the other.
