~> The mulligan feature is nice as it allows to try the shot again BUT costs 2 ball hits!
One has to determine their goals for playing the game and a bank account to support it.
The game promotes going for birdies in order to advance to the next level/tier. To maintain lower scores requires better clubs and golf balls. Those conditions translates into have a healthy bank account.
A down the road example: Moving into the Legend tier pretty much demands obtaining Level 96 and above iron sets, driver, and 3 wood. There's a large variety of competitive golf balls one may need.
Of course, you can pursue the game with some WGT golf balls as long as you map the distances and understand their limitations.
