class FavoriteGames(models.Model):

Answer 1

When you loop through the queryset you can access the game_id for each instance. You can't access it on the queryset.
You can loop through the queryset in the view,
favs = FavoriteGames.objects.filter(user_id=id_user)
for fav in favs:
game_id = game_id
or in the template:
{% for fav in favs %}
{{ fav.game_id }}
{% endfor %}
If you only need the game_ids from the queryset, you could use values_list:
game_ids = FavoriteGames.objects.filter(user_id=id_user).values_list('game_id', flat=True)

Answer 2

filter will return Queryset.So use get instead of filter. If multiple objects are there use filter, but you need to loop over that queryset to get each objects.
