Doesn't uninstalling v3 Arcade remove the database tables? Then re-install the product to start over again?

If you run this set of queries via phpyAdmin it will empty all your database table contents but keep the tables

TRUNCATE `v3arcade_categories`;
TRUNCATE `v3arcade_challenges`;
TRUNCATE `v3arcade_favorites`;
TRUNCATE `v3arcade_games`;
TRUNCATE `v3arcade_news`;
TRUNCATE `v3arcade_ratings`;
TRUNCATE `v3arcade_sessions`;
TRUNCATE `v3arcade_tournamentplayers`;
TRUNCATE `v3arcade_tournaments`;

Or running this should delete them altogether allowing you to re-import the product

DROP TABLE `v3arcade_categories`, `v3arcade_challenges`, `v3arcade_favorites`, `v3arcade_games`, `v3arcade_news`, `v3arcade_ratings`, `v3arcade_sessions`, `v3arcade_tournamentplayers`, `v3arcade_tournaments`;
