What is the diffrence between the number of games produced by Culture Brain that can be played on SNES and DS?
difference = SUBTRACT(SUM(platform_name = 'SNES'), SUM(platform_name = 'DS')); SNES refers to platform_name = SNES ; DS refers to platform_name = 'DS' ;
SELECT COUNT(CASE WHEN T1.platform_name = 'SNES' THEN T3.game_id ELSE NULL END) - COUNT(CASE WHEN T1.platform_name = 'DS' THEN T3.game_id ELSE NULL END) FROM platform AS T1 INNER JOIN game_platform AS T2 ON T1.id = T2.platform_id INNER JOIN game_publisher AS T3 ON T2.game_publisher_id = T3.id INNER JOIN publisher AS T4 ON T3.publisher_id = T4.id WHERE T4.publisher_name = 'Culture Brain'
