Currently, 2D sprite replacements are not as popular, so much of what's available among replacement packs are quite bland in the same fashion as Final Fantasy 6's iOS "remake" or RPG Maker stuff, but they're meant to be a proof-of-concept, no more. As of 2018, 2D sprite replacements have improved in quality with the release of several excellent 8-bit to 16-bit packs for NES.
