I would have preferred one of the larger box sets, like we've seen in recent years, involving more games. That's what was originally reported (the original report was that all the Finals games would be included, at the very least), and I was looking forward to it.
However, seeing the cost of this set, I can't complain. $30 is a very reasonable price. I'm sure they balanced making a more complete set (like they did with the Heat, for instance) versus price (the Heat set cost $75).
