It is largely believed to be responsible for stealing Xenogears' budget. Or Chrono Cross'. Or both.

In any event, that is enough to write it off as a crime against humanity. Those games are both infinitely superior to FFVIII.

Now let's see...things wrong with Final Fantasy VIII....
1. Gameplay is so easy that it makes me realize that we were all super dumb babbies growing up. The Junction System is more easily broken than FF2 with its "hit yourself to get stronger" strategy. Even if you don't use the card game, refine some Tents into Curagas when you head to Balamb and suddenly the game will never be a challenge again.
In fact the game is so insultingly easy that you never have to work at anything. Because they didn't think the Monsters-Level-Up-With-You thing through. Never Level Up, never fight smurfing anything + Junctions = Tapdance on every boss' ass. Suddenly you're Level 15 fighting Level 15 bosses while you have 255 stats. The game rewards you for not doing anything.

2. The Story is a trainwreck. I think my favorite part is something I realized on my last playthrough. If you go to Balamb at the start of the game and talk to some random kid you hear all about the legend of Hyne and the origin of Sorceresses. THIS IS NOWHERE ELSE IN THE GAME. Critical backstory here and only available from a random NPC at one point in time.

3. I don't hate Squall and I don't want to get into the argument about how sudden his falling in love with Rinoa was. None of that changes the fact however that there is a scene where he literally loses his goddam mind and screams at all of his companions. Selphie even asks if he's gone crazy. This scene is never spoken of again. I want to gather three of my friends and just scream "I DON'T WANT TO DIE!!!!" and run out of the room. If none of my friends ever seek me out after this or call a therapist for me, they are no longer my friends.

But I guess I'm asking a bit much here. I mean, the collective personality and significance of the non-Squall and Rinoa party members makes the FF1 party look like they're from frickin' Xenogears. You can't rely on Selphie or Zell or Irvine or Quistis to contribute anything to the damn story or to have a reason to exist really. They're all equally useless and could easily be written out of the game.

4. Seifer was the only good antagonist in the game and he vanishes for most of Disk 2 and 3. What the hell was up with that?

5. Ultimecia is more worthless than Zemus.
