There's been some grousing about the counters included in the Memoir '44 Overlord expansion but I think even owners of two M'44 sets can find a use for them.
Memoir' 44 has many good qualities, but portability isn't one of them. It's a big box and with expansions it can be quite a bit to haul around.
Using the counters, though, one can create a "travel" edition that will fit in a folder with the rules and many of the marker counters. If you use one of the paper maps it will be even more compact. You'll still need a dice pouch and a box for the cards but overall it's a much smaller package.
