Look, you say you're being honest, and I'll give you the benefit of the doubt. That being said, the sincerity is shortsighted. While Ultimate is one of the biggest achievements in all of gaming, it can't be seen as the bar for which others should aspire to. Sakurai has already gone on record saying that something like this may never happen again, which is why the team is going above and beyond and why they're going above and beyond the above and beyond with regards to brining characters and game worlds together. In other words, Smash Ultimate is an outlier among outliers.
Say what you will about your disappointment/dissatisfaction with Game Freak. I share some of that with you. But comparing its efforts to that of Ultimate's is myopic and ultimately shouldn't hold.
