To date I own a DMD and an SS - I am starting to think the gameplay on the SS is better than on the DMD.

So the answer is: it depends on the title and what your idea of good gameplay is. To me, it is the one that keeps saying 'play me and try to beat the high score' that has the better gameplay. This one will maintain my long-term interest.

If an EM can do that for me I would see it as a keeper. If it can't I would move it on.

That Mata Hari should be worth a bit as the EM version is pretty rare.

And Daniel, why don't you drop a few pins off to my shed - I will try to make them break down for you.
