YES!
And I'm like the biggest fan of 64 and Melee, but while Brawl was a disappointment, Smash 4 (on both systems) was just a HUGE downgrade for me.
I've said it before and I'll say it again, Sakurai is someone who's given way too much freedom, where he just tries to shove in everything including the kitchen sink, regardless if it's well thought out and top-quality or not. Then there's the awful long development times when Melee was 13 months (I know how that affected Sakurai, I wouldn't want that to happen to him again).
Melee had a harsh deadline as said, but they made sure that EVERY aspect of it was an utter joy. It wasn't perfect, but everything just took what was awesome in 64, made it better, and added cool new stuff in it also.
Smash 4 didn't even have much of a major adventure mode at all. Smash Tour was horrendous and even with that so called tutorial, I couldn't understand it at all. The visuals, despite being 1080p and 60fps on Wii U were pretty bad IMO, I mean what were they thinking with characters like DK for instance?
Trophies were really lazy when so many of them are practically Wii-grade models (and often mere rips at that) when in Melee, a huge chunk of them were very high-poly and felt like they were showcases of what the hardware could do at the time.
Classic mini-games like Break the Targets were completely changed (into Angry Birds? What?), there's still the missing Race to the Finish and Board the Platform mini-games from earlier entries.
Music, like Brawl, and so overdone where it's like 50% reused tracks and the rest is composed by like a dozen composers. When the 4 from HAL in Melee utterly blows them all out of the water to me. I cannot believe that Brawl had 41 composers and was still inferior to Melee's soundtrack IMO.
This is why I really hope Smash 4 does not get a Switch port and they just jump straight into 5 and go all-out in terms of pushing the system (Unreal 4 would be a great fit as BN already use it), I remember playing Soul Calibur 2 on GC and wanting Smash 3 to emulate that look, well what a coincidence! Do that with Smash 5 BN!
I know a lot love Smash 4, but man did I not like it, I mean it's DECENT, but that's the most I can say honestly.
I also just really miss HAL being in the series.
