Been thinking about this for a while and might as well post some more unpopular opinions from my side.
First of all, regarding the two current discussions:
I agree that Game Freak needs to slow down on the release schedule, and that there shouldn't be any more remakes. For better or worse, it seems like we are getting a break this year at least. Though I am okay with a yearly release schedule when it comes to games with low content (X/Y and OR/AS), games that I don't like (HG/SS), to an extent when it comes to games with average content (D/P and B/W) but not regarding games with a lot of content (Platinum and B/W2). For the games with the most content, I need more than a year to complete them and the break needs to be longer, though I prefer it to be that way in all situations. I also don't want to see any more remakes in the future because I have personally only found one remake pair we have gotten so far to be really good (more about that below), and I have never found a remake to be the best game in their generation. Remakes also usually don't add as much to the gameplay as new games do, so I don't see the need for them.
Regarding the current remake discussion: I have partly said it before, but I'll say it again. FR/LG are my favorite pair of remakes. They were really great improvements over the original Kanto games and fixed pretty much all of their problems. They also added many new and fun things like the Sevii Islands, VS. Seeker, Fame Checker, Elite Four rematches, Johto references as well as the ability to obtain Johto and Hoenn Pokemon. Then were also the only way to get several Kanto Pokemon in third generation (and maybe some from Johto, not sure about that though). Then they also kept all the good things the generation itself had introduced with Natures, Abilities, the reworked EV/IV system and the new box system (the one in Gen 1 is beyond horrible in comparison).
HG/SS are my least favorite remakes, and as I have said before, among my least favorite games in the series. Almost everything with them is just plain bad. They didn't fix any problems from the originals (level curve, Pokemon distribution, lack of training spots, uninspired story with bland characters, two regions instead of one) and I didn't care much for any of the new stuff they added, especially not the following Pokemon (though this is a very personal thing more than anything else). I feel like they were just fan pandering to Johto fans instead of being real games.
I haven't played OR/AS yet, so I'm not going to give an actual opinion on them (don't take anything I say about them as a basis for anything). Based on what I have seen and heard about them though, they don't seem bad, but they lack the things that could have made them so much better. In terms of remakes, they seem to be in the middle, not as good as FR/LG but not as bad as HG/SS. They are probably the best remakes in terms of playability by modern standards though. Probably good games, but as said, they lack the things that could have turned them into
fantastic games.
Overall, I guess my opinions could be summarized this way:
FR/LG: Good games and good remakes
HG/SS: Bad games and bad remakes
OR/AS (likely): Good games but only average remakes
I also read the Rival-discussion from a few pages back and I believe this is unpopular: Blue is my least favorite Rival in the series. He is just a jerk with no character development at all. That's not what I consider a good character. And it's quite bad for such an important character if you ask me. The reason he is a jerk is never stated anywhere either unlike for Silver where it at least was hinted at. And Silver also had a tiny bit of character development towards the end (in HG/SS at least, don't remember it being in G/S/C), which makes him marginally better than Blue to me (though I still find him to be the second worst rival). Blue was a better character in the Johto games in my opinion where he might have lacked character, but he was at least not a jerk.
As for what I thought about the other rivals... May/Brendan and Wally were acceptable, better as characters but not as challenging since you don't battle them as often (in R/S/E at least, OR/AS appears to have fixed this to an extent). Barry was really good and so was Hugh. Bianca and Cheren were the best. The X/Y rivals were, once again, acceptable. A bit sad that we didn't get to battle them many times (the exception being Calem/Serena), and their characters weren't very well developed, but at least they weren't jerks. Hoping the future Kalos third version/sequels will fix this. If not, I hope the remakes will...
Onto something else. I liked how all the legendaries in X/Y were shiny locked. That made it less stressful to reset for them since I would then not be at risk of being stuck choosing between a shiny which might have bad IVs and wrong nature or toss it and keep resetting for one with satisfying IVs and a useful nature. Now I don't have the best luck with shinies so I would probably not have encountered any of them as shiny even without the shiny lock, but still.
One other thing I liked (but in a different pair of games) was this: the fact that Hilbert/Hilda were never physically present in B/W2. The reason is that they are not "a strong trainer", in fact, they are not someone else at all. They are you. And they couldn't be present in the games, because there could not be two "you" (as in the player character) at the same time. I don't like the fact that Red (as in "the player" from the Kanto games) were present in the Johto games, I definitely prefer what they did in B/W2 and if there are more sequels in the future, I hope they follow that route.
I realize I haven't gone over a lot of the things I disliked with HG/SS here, apart from the games as a whole and the useless following Pokemon. So here is another thing which is unpopular. I think the touch screen usage in HG/SS was terrible, and I also think those games has the worst UI in the series. The main problem I had with it was just that it was so slow. It slowed down momentum and decision making which is a terrible thing to do in a game, the
menus should never slow down the playing as a whole. There was no excuse as for why it was so slow either as it was much faster in 5th Gen even if they were on the same console. There were even third party games which used the touch screen better than HG/SS did. I also found it to be very messy and badly organized on the whole, the buttons felt out of place at several points. The PC menus were beyond horrible, everything was so badly done and it did once again slow down everything for no good reason. I'm really glad they improved on the touch screen usage in 5th and 6th gen. Game Freak started badly with it, but they have improved on it a lot afterwards. Which I suppose you can say about many other things in the Pokemon games.
Something else, which is related to the Johto games again, is this: I dislike the idea of there being two regions (or even worse, more than two) in the same game. I found it to be very badly done the two times it has happened, and I can't see how it ever would work with Pokemon being the game it is. Having two regions in one game causes massive problems with the level curve and pacing with no real solution available, so I hope it never happens again.
And one final thing. I don't know if it is unpopular or even relevant to the thread, but seeing some other recent posts made me want to say it. I like how
Pikachu315111 resonds to most other posts in this thread in order to create discussion as it makes the thread and the forums more alive and better. Not to mention the fact that his posts are very well-written and have lots of thought behind them. Keep on being awesome, you magnificent discussion-creator.
