I'm still interested in following what's new though after my interest increased before the reveal of SwSh, it is now waning again. Pokémon was my absolute favourite franchise when I was a kid, watching the anime and collecting cards, then playing the games from gen 2 onwards; I stopped watching the anime around the beginning of gen 3 and stopped collecting cards after that gen, but my peak interest was for gens 3 and 4. Diamond is one of the games I've played the most, and then came Platinum and HeartGold which are imho the peak games of the franchise.
Gen 5 was when my interest started to wane. I wasn't a fan of many new Pokémon in the beginning (most of them later grew on me but due to the large number I still think there are many good designs but also many forgettable ones) and BW felt like a step down from Platinum/HGSS, I appreciated the brave move of all new Pokémon in the main storyline but I didn't think it worked as well as the mix of old and new of RS and DP, also it started removing features and the trend towards linearity. Still a good game, but I didn't enjoy them as much as the past games. B2W2 were better, but by then I had moved on somewhat from the franchise and I was playing other games a lot more. It all got worse with the following generations, which I only played a lot later than release date (gen 6 only when gen 7 was almost out). SM wasn't only when my interest in Pokémon was at an all-time low, but at the time I was also little interested in video games.
In 2017 I got a Switch, at first only for Mario Odyssey, and that plus the then-upcoming titles made me interested in video games again; knowing that a Pokémon game for Switch was due to be out obviously raised my hype (only to be disappointed at the reveal of LGPE), though I still kept high hopes for SwSh, and that's also when I started lurking and then posting here. My new interest in Pokémon made me play again the earlier games that I had enjoyed so much, as well as fan games - and I still enjoy playing them. Honestly my interest in SwSh has been decreasing more with every reveal, as it doesn't seem to be the game I was hoping for it to be, and by now I'm 100% sure I'm not going to buy it in the foreseeable future, so I'm kinda puzzled on how I'll feel about Pokémon in the future. On one hand, it has been one of my favourite franchises of all time and I enjoy the older games (FRLG, Emerald, Platinum, HGSS, and gen 5) a lot, but I can't get interested in the new titles even if I try to like them.
