Having to wait for a good product is always better than instant gratification of a bland one.
The last Pokemon games to be chock full of content while also being full of love was HG/SS. Unlike other developers Game Freak doesn't love making a good game just as much as they love making money. They're content with rehashing whatever they can, as fast as they can, with very little depth and features that won't return in new entries.
Look, SuMo are the best Pokemon games story wise since BW, and they have more organic region design. That said, they just don't push the series to new heights. Game Freak doesn't make Nintendo level quality games and I think it's time that changes. They need to start loving what they do, and put their heart into releasing each game with enough content that they'd be proud if it were the last entry. That's the Nintendo design philosophy. To release a product that is complete from the time you start playing to the time you finish. The gameplay should always at least be just as good in quality as the last best entry.
That's why I wanted it to be a Switch game, so Game Freak would be forced to take a release hiatus and crack down on making a game and using the new technology to push Pokemon and its gameplay mechanics to whole new levels.
Ultra SuMo clearly aren't sequels, and that's where my disappointment lies. I would have loved sequels like BW2, that would've been a worthwhile purchase. Instead it's clear that we're getting Pokemon Sun Platinum/Emerald and Pokemon Moon/Emerald Platinum.
At this point, I'm probably going to pass unless they actually listened to the massive fan feedback/critisism last year and give us a difficulty slider and a large post game. Trainers should start having teams of six by the time your team is level 30, and a level scaling mode would be nice to keep players that want a challenge to ruin it by grinding. In that mode enemy Pokemon would always be at least the same level as your Pokemon, and boss Pokemon would be 2-5 times higher in level. Again, just an optional mode for experienced players that you'd probably activate in the settings category that would give you a prompt saying "This will make the game very hard, you sure you want to choose this mode?" In order to keep kids from making mistakes and turning it on without knowing what it was.
