Looking back on the MvC community clowning on the guy who said "characters are just functions", I really wish people took it beyond the FGC and clowned on "gameplay first" stans for being just as self-righteous and single-minded as graphics fans. Because honestly, gameplay is nothing more than a function.
Still though, you might as well build on what's already perfect than try so hard to be original that it ends up not being fun (which Sony tried earlier with PlayStation All-Stars).
