I'm sure MMr will be a fine game. I'm hoping the platform will be a success so we see future remakes. But no matter how you spin it, an MMr is not an MM. It will have better sound, but that's it.
I'm very glad that many who want the gameplay of a MM in their home will be able to have it at (what was a year ago) a reasonable price.
My original plan was to sell my MM and get an MMr. But there are enough subtle changes so that MMr is not going to be the replica many were hoping for, though for many it will be "good enough".
I think we are going to see a renewed interest in originals (at more reasonable prices). I now see more value in having an original than I did a year ago.
