Well, there's one thing this game did in my brawl perception, before ssb4, I didn't like the global repping of brawl (several inconsistencies...hated SSE because of that, too much of long rant so, going to skip it, but I did told that rant months ago).
Now, I HATE EVEN MORE BRAWL!!!
Really, this game did what I judge that comparing to brawl, it's crushing it. Please note that my reasons has absolutely nothing to do with gameplay but mostly with the visuals, audio and the global repping. I liked the artstyle a lot more, the music are even better repped, there's so much more contents, the repping is way broader and finally, the game overall feels good (brawl had some...annoyance like long classic and the loading times....).
My complain on ssb4 is so low that it emphased my negative opinion on brawl a lot more.
So, I basically went from mixed review to I hate brawl.
I do remember but now, I don't want to
