Yes, 3 on 3, half is ideal but 4 on 4 is great too. At our gym there are a 6 hoops but only the 2 from the long sided court are decent. The older guys, 8-12 of us, get 1 of the good nets and pretty much play amongst ourselves. Once out of every 3 times, these 2 twins show up. They're both 6-4, 250, bigger than any of my friends or me. They are decent players but are slow, lumbering, black holes. Occasionaly we tell them they can't play for a couple of games then they eventually start playing on our court.
Also, the idea of a 1on1 for the court is a good proposition.

For OP, standard, the kid overreacted especially considering that some of your friends were crap.
