Final Fantasy

Final Fantasy's identity crisis has yielded declining sales, with FFXVI selling only 3 million copies in its first year—30% fewer than FFXV and 50% less than the average mainline entry before FFXIII. Each game abandons the last's mechanics, from FFXIII's linear corridors to FFXV's unfinished road trip, making it the most mechanically inconsistent franchise on this list. Compared to #8 Far Cry, Final Fantasy trades on legacy with no modern definition, struggling to match even Ubisoft's iterative formula.
