For the past 4 1/2 years, one of life’s more unpleasant annoyances has been having to buy $12.50 worth of points to buy a $10 game. We don’t know exactly when, but very recently Microsoft changed the pricing structure for the procurement of Microsoft Points in the North American market. From the Live marketplace, points are now available in 400, 800, 1600, and 4000 increments for $4.99, $9.99, $19.99, and $49.99 respectively. These align themselves much better with the current pricing structure of Live Arcade titles than the old standard of 500, 1000, 2000, and 5000 point increments.
It still doesn’t fix the possible conniption you might have if, say, you have 380 points lying around and you have to spend $10 to buy a 800 point game because 400 wouldn’t cut it, but I had all but given up on Microsoft ever changing it by this point, so we can’t be too upset.
