Since they share a studio, here's Max's take on Smash 4:
He's not always right when it comes to mechanics (especially since he knows he's not an expert), but look at how reasonable he is:
Acknowledges that the game speed is genuinely faster at about the same feelings we have all concluded (about 25%~ faster), but focuses on why there are still issues.
Acknowledges that this is an old, old build, and things can still improve.
Acknowledges that Brawl is the best selling entry, and regardless of whether or not he agrees with the design direction, it will still influence the next product vastly.
I won't spoil everything, but it's worth listening to his opinion on it to compare it to the same guy he shares a space with.
