What we played? Guess once: Mario Kart 8 of course! Four people could play at the same time.
Later in the night (we gamed for 9 hours) we tried some other games, including Tokyo Jungle, Gal☆Gun and the one in the last picture: Arcana Heart 3. You know, the game that Swedish distributors took off the shelves because of “suspected child porn”. Haha, or something.
