[User] Can you provide a list of all players who have acquired at least one item, along with the item name, its type, and the title of the game that item belongs to?

[Assistant]

[User] Actually, I'd like to only see cases where a player has acquired more than 2 different types of items. Can you adjust the query?

[Assistant]

)
GROUP BY pi.player_id, items.item_name, items.item_type, g.title;

[User] I'd also like to know the total quantity of items each qualifying player has acquired. Can you add that to the results?

[Assistant]
SELECT pi.player_id, SUM(pi.quantity) AS total_quantity

)
GROUP BY pi.player_id;

[User] Can you also display the country of each player if I had such a 'country_code' column in a 'players' table? Show it in the result along with the player_id and total_quantity.

[Assistant]
SELECT pi.player_id, p.country_code, SUM(pi.quantity) AS total_quantity
