Also developed by a 3rd party.

Camelot, the only entry in the franchise made by them. But it's owned and published by Sony so just like Mario Golf (also developed by Camelot) it's first party.

The original post says Sony relied on 3rd party's for success, so I feel 3rd party developers also count.

Imagine it this way, let's say all of Nintendo's franchises aside from Mario Kart was made by 3rd party's and Mario Golf was made by Camelot wouldn't you agree in this case?
