He's saying that the importance of designing trading cards now is very very very unimportant compared to tasklist at hand before release.
I don't really think that's an opinion, more like common sense
Exactly this. I probably was being a bit too harsh, though. Sorry about that.
You can only release the game and make a first impression once. Cards can come out any time at all afterwards. I probably would indeed collect a full set of cards for this game, instead of selling them like I do the others.
The type of person who cares about these cards is already following the cards closely and will notice when cards come out. I don't think the amount of people who would pay $40 for the sole reason that a game has cards is very large, but those who exist are already following the cards.
There is no good reason to spend the dwindling pre-release time working on cards, when they could just as easily be done post-release.
