Inca Big Button and cost versions
Royal Festival is an Inca Fortress Age Big Button technology at the Community Plaza. Its Knights of the Mediterranean cost is 250 Food, 250 Wood and 250 Coin; an earlier Definitive Edition version cost 300 Food, 400 Wood and 500 Coin. It delivers one Maceman for every four minutes of game time, up to 30 minutes, so the reward depends on elapsed match time rather than a continuing queue.
A delayed force reward
The technology can deliver a larger group later in a match than early on. Consider whether Macemen fit the army and whether Plaza workers can be spared. Do not treat the displayed cost as universal across Definitive Edition patches; check the installed version. This is an Inca-specific Plaza option, not a standard upgrade for other civilizations.
