I didn't play RSE but I was pleasantly surprised by the fact that the encounter rates were drastically reduced in Gen VI. Also the Hoenn surfing music is pretty good which is nice.
New unpopular opinion: Happiness was a wasted idea.
As some of you may know, I'm currently trying to complete the National Pokédex, meaning that I have to evolve a lot of Pokémon through happiness, which is itself pretty annoying.
What really got to me, though, is that as I was thinking about happiness, I realized how little an impact it made in-game. 99.9% of the time, there's no difference between a lifelong partner and a Pokémon you caught in some nearby tall grass (except EVs, but those represent training, not friendship). The few exceptions include evolution, increased Return power, and a ribbon. To make things even more ridiculous, they introduced a new system in Pokémon Amie t
hat had absolutely no relation to happiness, making it even more irrelevant. At the very least, I want to see proof in battle of how happy my starter is.
