Is this part of this game series, or a different game?? I'm unsure if this counts as a serpate game or not, or what the different is between the 'combat of' and 'battle of' series

Super new. I really enjoy watching speedrunning videos and think the whole idea is cool. I just remembered an old ps2 game i used to play and so i thought i should try speedrunning it, because its not too competitive at the moment. i have no idea how to add a timer or record gameplay but idk ill figure it out
