I was really really down on Sun/Moon to the point where I didn't want to give GameFreak any more money... but I caved and bought Silver since it's my favourite gen and I can bring them into whatever Gen 8 happens to be on Switch hopefully.
The big thing I'm taking away is how much I miss the different sprites that each game used to have. Some of the sprites in these games have so much more personality. I mean, look at this guy:
I've never been a huge Slowpoke fan but that sprite made me fall in love and use him in this playthrough.
I would hope that GF would stop focusing on terrible and poorly implemented "Innovations" like pokepelago, pokefinder or ride pokemon and just put more effort into making the pokemon have different stances or animations. I know it's a lot of work but now that they don't have to re-draw the sprites since they have such detailed models it would go a long way to breathing life back into these games.
