Smash Remix is full of options and new features, making the old Smash Bros. feel fresh again. There are a lot of well-designed stages, the new characters control well (although they feel unbalanced, Giga Bowser, for example). The remixes are good to hear in the Smash soundfont and it all feels very polished, like if Nintendo themselves made it.
I'm looking forward for what the developers bring in the future releases.
