E-sports games are mostly eliminated by double loss. However, since it is a points competition rather than a championship competition, it seems more reliable to adopt the method of eliminating the group round robin list and give points according to the ranking. If the number of participants is sufficient and stable, the tournament system can also be considered. Refer to the major football leagues for details. The GSL system of StarCraft II is also very good. In the case of KOF97 personal competition, the so-called tactical victory does not seem feasible. If you play in a team, you can add resurrection (resurrection of a defeated player)/substitution (when both parties confirm the contestants, you can use another player who is still alive to play the game instead of the current player)/prohibition (prohibiting the other party from choosing a role)
