How to return the number of rows of mysql sub query

Question

I have the following SQL query:

SELECT games.id, games.GameTitle FROM games 
WHERE EXISTS (
              SELECT filename FROM banners 
              WHERE banners.keyvalue = games.id 
                AND banners.filename LIKE '%front%'
             )

which is not entirely correct for my use

what i need is something like:

SELECT games.id, games.GameTitle 
FROM games WHERE EXISTS (
    COUNT(SELECT filename FROM banners 
    WHERE banners.keyvalue = games.id AND banners.filename LIKE '%front%') > 1
    )

i.e. select only when the subquery receives more than 1 row.

Answer 1

Just:

SELECT games.id, games.GameTitle 
FROM games 
WHERE (
    SELECT COUNT(filename)
    FROM banners
    WHERE banners.keyvalue = games.id AND banners.filename LIKE '%front%'
) > 1

Answer 2

SELECT games.id, games.GameTitle 
    FROM games 
    WHERE EXISTS (SELECT COUNT(filename) 
                      FROM banners 
                      WHERE banners.keyvalue = games.id 
                          AND banners.filename LIKE '%front%'
                      HAVING COUNT(filename)>1)
