Absolutely. I'm only an hour or so into the game, and already I'm loving it.
Each set of games has a distinct feel about it to me, something it excels at that makes it unique to the rest of the games.
Gen 1 was the O.G., it was brand new at the time and made RPG's, something I hadn't been much a fan of beforehand, worth playing.
Gen 2 built off of the legacy of Gen 1 and introduced its own history and heritage. It felt like a true sequel to RBY.
Gen 3 was advancement into new territory, switching up gameplay with stuff like natures, double battles, etc. It also started the trend of the villains posing more of a threat to the world around them.
Gen 4 was a refinement of what came before. Better music, better graphics, more things to do on the side, higher stakes with the villains, etc., it ramped up previous elements into a unique experience.
Gen 5 was without a doubt the most mature of the games. While there are indeed graphics advancements that make it play really smoothly and make the whole thing look good to the eyes and sound good to the ears, it was the more developed narrative that drew me into these games.
I don't know what to make of Gen 6 yet, obviously; I'm only an hour or so in. But I'm already seeing many new advancements that I really like, and I look forward to what it has to offer.
