dougthonus You will always have to release the batches manually, so they won't start automatically once the first game finishes. If I remember correctly, you can release all games in a batch with one click, but you always have the option to manually launch games. Having only one game for everybody at the same time also depends on number of participants/games. If you stick to the magic numbers where this works, it can be done.
It is not all automated, you will have some management to do on the tournament.
