Top three is pretty hard.

1. TotAN
2. CV
3. WH2O

But there are so many more and I haven't played them all so......

LotR definately rates, Safecracker is very interesting, I love Pinball Magic, Scared Stiff is great fun and I like Spiderman and Pirates of the Caribbean too.
And that's only some of my favourite DMD games not to mention all the cool SS games.

Maybe you say top three DMD, top three SS, and top three EM, 'cause really they're all in a class of their own.
