Both are awesome games and play very similar. I have owned 2 original MM's and still have one. I've owned an original AFM and a remake. I prefer the remake Le as the topper kills it. Sold the remake, miss it and most likely grab another if a martian green comes up again which I am sure will.
MMrRE lights are too much IMO overkill. Personally I never liked the play of the MMr, it didn't feel like my original but AFMr plays great and MBrLE is amazing and solid. Can't wait for the next release. If it's TAF or IJ and will grab an LE for sure.
