I love the Bowling RPG idea but I can't help thinking this thread's been derailed a little.
Played my brother in a round of Tiger this evening and he thought the alligator wrestling thing was excellent too. He thought it would be quite difficult for an indie, but then we remembered that Yakuza 3 (and possibly the rest of them) had a full eighteen hole course included as a mini game
. That was quite an achievement for a mini game.
