I am figuring on playing Terranigma again someday, once the Redux patch has finished cooking. Also will be using MSU, for that CD-grade audio.

IMO, La-Mulana is likely to be among the very best metroidvanias. However, it is very much a love-it-or-hate-it type of thing. All the greatest games tend to be that way, it is just an issue of people discovering their compatibility.
