I agree, I have no reason to buy LV just yet. Especially since I don't like Steam.
On to the bowling alley.
You click a button to start the game. You are set in position where you place a ball on the floor. You look down to set a fake explosion off which sends the ball down the alley.
About halfway down the alley, there are a set of lights. By turning your view, you select which light you want to set the 'second' fake explosion at. As the ball passes them, you look down again to set off a corrective fake explosion which hopefully sends the ball smashing into the pins.
You will get credits based on how many pins you knock down. Its actually pretty fun.
As with all my mods, this will NOT require the script extender FOSE.
