We'll TRY to be civil about this. Hopefully, this won't spark a flame-war but opinions can have that effect and this will be a highly opinionated thread.
At least you realize how crazy this can get, make sure to keep your finger on the delete button if things get out of hand.
Anyhoo, my choices...
In terms of the former, I don't hate any of these games, I just can't get into them:
-
3D Zelda (excluding Majora's Mask): Never could get into 3D Zelda, and I have no idea why. I can acknowledge them as quality games, but I myself can't get into them, and aside from Majora's Mask, I've never finished any of them without cheating. Maybe it's because I was only 3 when Ocarina of Time came out, but I never saw what's so great about it once you focus on the story/presentation/dungeon design/whatever else makes up the game. Yes, I realize how revolutionary it was with the lock-on system, but something being revolutionary means nothing to me if I'm not having fun, and I wasn't.
-
Final Fantasy: I've only played 2 of the games, 4 and 6, and I didn't complete either of them. The soundtracks and stories were fine, but I couldn't get into the battle system. I'm a lot more of a turn-based battle person (which I don't count ATB as). And considering how the later games look and seem to play, I have no desire to play those. I'll stick to Dragon Quest, thank you very much
-
The Tales Series: I own Symphonia, and I couldn't go any farther than the first major boss fight (some tall green thing). Not because it was difficult, but more because I just couldn't stand the battle system. Real-time is not for me, and though the story I had gotten at first had a good setup and I liked the characters right out of the gate, the combat just didn't appeal to me. And since combat is what most of your time in an RPG is spent doing, that pushed me away very quickly.
In terms of the latter:
-
Arc Rise Fantasia: I wouldn't say this game is hated, per-se. But many people, especially professional reviewers, called it garbage because of the voice acting and grinding (A lot of them didn't even play the game past the 12 hour mark, and the main game is around 80 hours). The voice acting is an easily remedied problem (Assuming you don't enjoy gloriously bad acting, and it gets better as the game goes on), and the grinding is not nearly as bad as games like Dragon Quest (which is praised like crazy), so that claim really holds no weight. Plus, there's no unnecessary extra mechanics to level-up, use new weapons (I'm looking at you FF XII), or learn new abilities. Plus, the bosses actually require strategy instead of brute force, something most popular JRPGs seem to lack.
Most other games I would list don't actually have that many people who hate them.
