I've recently checked out the previews of 100s of 3D-type games. Even dl'ed 7-8 and played through. I think my standards must be much too high because I won't continue with any of them.
There HAS to be a story to frame the action. This frame should be ultra-realistic because the action is often contrived, body proportions unrealistic, and character motivations unbelievable.
There is better artwork elsewhere (pron comics, erotic fantasy art). There is better storytelling elsewhere (erotic/pron stories can be extremely well-written).
Where 3D shines is the visuals. DMD has stunning visuals (far better than most). But the remarkable D, with her looks (her model has been near duplicated a dozen times but DMD D is best) and personality are a dual treat a gamer rarely if ever encounters. I love her so much that I play DMD totally disliking the other two main characters--MC and Elena.
Take the visuals and D away from DMD and not much good remains. Sure the storytelling is a cut above most other 3D games but it's a contest to determine the tallest midgit. Whoever has much viewing experience with these games, DMD must seem like an oasis in a desert.
