Memory and perfect information games

Well, it seems a good way to improve the use of memory. Maybe.

But if you are not more precise and describe the game it is very difficult to say something more precise. Let me judge by myself what is "low memory required".

If you say what game is (are) I can search information about rules and system and give a better feedback about the topic.

I agree that serving as a useful memory-improvement exercise is one possible reason - I suppose this could be loosely described as an "educational" aspect. The two games that I specifically had in mind are Indigo and Burgenland, both by Ravensburger. I should add that in both cases I've so far played them as two-player games, which obviously does simplify the memory exercise, but given the small number of hidden elements to track in each and the four-player maximum limit on both, the mental book-keeping should not increase too drastically. Also, as mentioned before, I enjoy the games and the memory element is not particularly irritating, it just doesn't do much either way for me unless I'm being lazy and not keeping track properly (then there is some added tension). On the plus-side, in both cases the screens are rather pretty and double as a player's crib-sheet for game-rules.

Let-off: the point about hiding victory points to keep trailing players from feeling disheartened is probably a good one - even if one has perfect memory, not having the evidence continuously visible does soften the psychological blow, perhaps enough to keep losing players from lising interest. However, one thing which I wondered about is whether this memory-dependent feature doesn't actually disadvantage younger (children) players, who I presume are less likely to acurately remember than adults, and who are probably also going to be weaker strategically. Any further thoughts?

Ok, so if I understand you correctly, you're saying that although the "hidden information" is not really hidden, the fact that these games are usually played casually and that people tend to be lazy and distractable by other features of the game (and perhaps because this sort of book-keeping is just less fun than strategizing, etc), in practise it works pretty well. I can see that this is true, as I've certainly often lost track of scores slightly because of laziness and/or distraction by tactical issues. So although I might find it a little inelegant, it will usually work, and at worst do no harm. Though if I were to do something like this I'd probably not use it for victory points (perhaps resources) and I'd combine it with a random starting "hand" - which would add an element of uncertainty which I'd personally find appealing.
