In all fairness, you pay a lot for golf IRL...
Start with the equipment, garment, shoes, gloves. Next, you spend gas driving to the course, pay an entry fee - probably not less than 10 $, mostly a lot more. And you pay for your balls which you may find in the rough sometimes, but often you lose them or discard them due to wear.
These costs are much higher than a few sleeves here. My best guess for WGTland is 5 rounds of 18 holes with one sleeve, so it's 0.02 $ to 1.50 $ per round.
And don't say, "you can't compare it" - you started the show.
To me. the realism of the game is good but it's limited, and one limit is this "ball usage" thing. I consider it an entry fee, and I'm glad that I'm the one to determine this fee. I may play for free or I may play a dollar or more per game, as I like it!
Those who say, "I lose too much in balls" only have to shift down until it fits them!
