In many such games, the memory element is completely unconnected to the other portions of game play, and many players would just as soon do without them. A bigger reason seems to be simply habit. For someone who has always played Acquire with closed holdings, that's just the way the game is played. Anyone who suggests playing it differently is well, just not playing it right. Unfortunately, for some games, the final explanation is the fact that the hidden, trackable information was introduced to fix a problem.
Some games are unplayable with fully disclosed information.
But the problem is still there, for players who are good at tracking. Others might play the game lightly and enjoy it, not seeing the flaw that is clear when it's played with open holdings. Worse, they seem to resent those who point out to them that the game falls apart if someone is tracking information. The defenders of hidden information claim that it is the trackers, not the game, who are responsible, and that they shouldn't be paying so much attention to the game that they break it. I can't accept that.
