As far as Pokemon go, Hoenn probably didn't introduce more of my favorites than any other region (that would probably be Unova), but it did introduce most of the ones I like the best (my favorite Fire and Water starters, four of my favorite Ghosts, two of my favorite Psychics (one of which is now a Fairy-type ^^), and my most favorite of all, Mawile, just to name a few).
As far as the region itself, I think it's interestingly diverse and my only real problem with it is I prefer regions with snow.
As far as the Hoenn rivals, yeah, that was a letdown.
Overall, I like Hoenn. --- Official Bride and Wife of Noire (of the Fire Emblem Awakening message board)
It's my favorite generation in terms of pokemon designs. The only 3 I hate from this region are Spinda, Luvdisc, and my personal least favorite gen 3 pokemon, Lombre. --- Mentions of Zangoose since 6/27/2013 as of this post: 24 Official Shadow Zangoose of the X board!
OH... You're referring to Gen 3's Dex? Yeah. Gen 3's Pokemon were overall the best. --- I'm not easily impressed; I'm usually oblivious to whatever's in front of me. Pokemon White 2 FC: 3139-7420-3142 - THIEF
Hoenn Pokemon are good, Hoenn as a region was pretty forgettable.
Really? I found it the MOST memorable. It had a lot of interesting locations, and the whole sidequest with the Regi ruins was awesome. It was one of (I think) two regions with a desert, and Sootopolis was a very unique town.
The only thing I didn't like about the region was that there was so much water, but that would have been fine with more Pokemon variety instead of just Wingul, Tentacool, Pelliper over and over again... --- "My favorite color of poop is seven." - Seanbaby, cracked.com The Official Nox of the Kingdom Hearts 3 Board
