[M] [R]. Determine the number of players based on the CSI. Indicate in the field the maximum range of concurrent players (e.g. 1, 1-2, 1-8). If the video game is massively multiplayer, indicate "1-many" in the field. If the video game has additional modes (e.g. local or online competitive/cooperative modes) record the number of players for those modes by repeating the element. If the number of players is unknown, record “unknown”.
