A considerable improvement from the first.
After NES Remix, I badly wanted a sequel. My main concerns with the first Remix were that developers EAD Tokyo and indieszero focused on Nintendo’s 1983-1986 Famicom line-up, which has not aged well. This second Remix, like all good sequels, takes what made the first game so great and improves upon the flaws. They also threw in backwards Super Mario Bros. with Luigi physics and a Nintendo World Championship mini-game if you own the first NES Remix -- how can you say no to that?
