it is an enhanced port.It's definitely a port, but it's a great way to make the port have value outside of being a port.
2 new fighters vs 64 ports from previously launched games. pointing out things like "the wii fit trainer has a new facial expression" in no way qualifies to me as new. TLoU got new textures when it was ported to ps4,.. it's still a port even though some work was done to polish the port. the reason everyone is saying the smash part was boring is because nintendo harped on every minute change to try and convince you they actually worked hard on this port. but..
..this was developed fast and cheaply. port.
Disappointing for people wanting a new Smash but great for people who love old Smash.
