Um, this isn't a case of, say, Capcom milking Street Fighter to death in the mid-90s w/ repeated, marginal, updates on SNES and Genesis (and PCE in Japan)--almost all of these games are radically different with the only common denominator being that they share a plumber w/ a red hat as an avatar, so why would anyone care?? (Unless they have it out for red-capped plumbers, in which case you need professional help.)
