I've been following this sight for about four months (since I got the bug to buy my own pin). I've gone back and read a lot of old threads. From what I've read, it seems that Stern pins often start off with basic code and improve with updates. Some are eventually lauded as great, while others are just hanging on. But all of them seem to have exhibited the same pattern from the reviews.
How many games have you seen go from bad to good, and how many stay bad? How do you know when Stern calls it quits on the code and a game is finally finished? For example, GotG just got a code update that fixed some serious gameplay flaws, but I wouldn't consider it finished. From posts, it's a toss up as to whether or not it will get another one.
