They all seem to although MM6 is my favorite of the group. Wish they would have offered all the MM even if it meant 20 dollars. not sure why people slam the graphics on MM6. They still hold up pretty good for a game its age. I like that all 6 are playable now without the need of putting a disk in. Hope GOG can get tons more oldies as I tend to play those more and for 10 bucks will gladly pay.
