Advance GenerationThe hallmark of sprite-based Pokémon gaming, Ruby, Sapphire, and Emerald set you off on an adventure in the watery Hoenn region with tons of diverse Pokémon to discover. Fans of Kanto can reexplore their favorite region in FireRed and LeafGreen. Here you'll find other fans who enjoy talking about the Pokémon, strategy, and techniques to master this generation.
Emerald is by far my favorite game of all time, so I will go with R/S/E. The region of Hoenn was simply breathtaking with all of the beautiful cities, routes, and towns. I loved how the region was filled with water to surf on and dive into. There was nothing that I found wrong with these games at all. They were absolutely perfect! My favorite Pokemon, Castform, was also introduced in these games, so without a doubt R/S/E > FR/LG
Ruby, Sapphire and Emerald definitely. I never played FireRed and LeafGreen, and Ruby was the first Pokemon I game I ever played, right on my birthday in 2003 when I had only just turned 11. I loved the game so much I was so excited for the next generation, and Hoenn is such a memorable but unique region in its own right.
I prefer Ruby, Sapphire, and Emerald. Unlike FireRed and LeafGreen, all locations in these games had something unique that set them apart from each other. For example, Fortree City had treehouses, Slateport had the Slateport Market, Lavaridge was known for its hot springs, and Mossdeep was the home of the Space Center. Also, the storylines of these games were quite engaging.
FireRed/LeafGreen, by far. Not only are they faithful remakes of the great games that started this franchise, but they also doesn't include any of the 3rd generation Pokémon which in my opinion is when things started going south as far as quality and charm goes (in my opinion).
LeafGreen is an incredibly good game, and I like a lot of the pokémon in them...but Hoenn clinches it for numerous reasons. Emerald was my first game, Hoenn's a lot more varied (although to be fair tech wasn't available in 1st Gen, they didn't want to change too much in the remakes), Hoenn has some of my favourite pokémon (i.e. Ralts, Lotad), Emerald has Battle Frontier...I could go on.
EDIT: Moving sprites. Particularly as I started with Emerald, LG's static sprites look just...wrong.
While it was nice to have FireRed and LeafGreen for nostalgic purposes, I simply prefer Ruby/Sapphire/Emerald for having way many more features, such as weather outside of battle, contests, being able to plant berries, secret bases, etc..
R/S/E were the ones that I waited for the most. When they did come out, I bought both Ruby and Sapphire, and really enjoyed them. I didn't play much of Emerald, but I really liked that as well. Fire Red and Leaf Green were good too, but I didn't like them as much as the original R/B/Y.
I prefer all of them, I enjoyed them all.
I love Hoenn, but Fire Red and Leaf Green is great too.
But if you ask which one I liked the most, I'd say Emerald.
I liked it the most because Battle Frontier, Match Call and of course, Hoenn!
I have only played Emerald and Firered so far, but I cannot say I prefer one over the other in terms of their series.
Most of my favorite Pokemon come from the 3rd Generation and Hoenn, which is my favorite region so far on top of that. Hoenn is unique from the other regions, the water travel is a big part of the R/S/E games, and I enjoy that. FR/LG on the other hand, have of course the nostalgia. Growing up with the original anime and Pokemon boom, Firered was the first Kanto-based game I played. (If you are not counting the 64 titles) I enjoyed the game play of Firered more then Emerald, and feel I ran out of things to do besides evolving Pokemon way before I did in Emerald. I voted for Hoenn, more pros then cons compared to FR/LG for me. (for the record, Having FR & Emerald for both a year and a half and I still have many things to do in Emerald)
Definitely Emerald for me. It had an excellent story with a good variation in Pokemon and movesets. On top of that, you could re-battle Gym Leaders and have the Pokemon Frontier challenge. The Elite Four is strong also, but if you knew their weaknesses you can easily dominate them. On top of all that, you had very intriguing and powerful legendaries, and contests if you wanted to... Show your moves!
