These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Oracle of Tao
Abandon Shipping: Nevras has about three childhood friends. One is a girl from his town, and the other two are soldiers in the royal guard. But one of those soldiers is a guy with the no male hormones, who Nevras found out about by bathing with.
Angst Dissonance: Possible, the main character does do a healthy dose of whining, since she has amnesia, a life characterized by poverty, and God keeps asking her to do things.
Come for the X, Stay for the Y: The main story might be initially what gets you hooked, only to find that you do a bunch of sidequests instead, or make money to upgrade your tent to a portable mansion.
Creepy Awesome: Ambrosia's mirror half. She actually manages to act as a sort of conscience for Ambrosia, making her aware when she's lying to herself or when she is about to cross a Moral Event Horizon, she has at least one scene where she's doing some seriously good fighting, and while Ambrosia tends to be angsty and repressed with her relationship with Nevras, her other half seems to be ready and willing for one. In the same token, she murders people within the first five minutes of her initial appearance, and in an attempt to warn Ambrosia about something, treats her to a Black Bug Room.
Ambrosia. God-Mode Sue is averted, since she only has her godly powers in plot events, but her Yin Yang powers are part of battle and the game. She can and does actions of great good or evil, with little regard to some of the finer points of character development. Lampshaded at one point, where Ambrosia actually points out that that she never really had to work for her powers, and it seems more like a delusion than Real Life. It turns out she's half right, in the weirdest possible way.
Otherwise downplayed. There are clearly other characters in the story that have their own strengths and weaknesses, and for much of the game she has no powers at all. Still, the whole "only one who really exists" thing is more than a bit weird and unbalancing. Not to mention, the universe can't exist without her.
Only the Author Can Save Them Now: It seems this way, due to a game balance issue, where magic is more potent than physical attacks. You tend to win if you use the right magic, while you tend to lose in the game's beginning if you use physical attacks. This crops up in the later game mainly in the case of epic bosses.
Padding: Plenty of the dialogue could be cut down into more manageable length. Along with much of the map, and some of the levelling.
Rooting for the Empire: You can certainly do this. The main villain is a poor misunderstood demon that got booted out of town, and sealed in a jar.
Shocking Swerve: Holy crap. The final enemy is impaled by one of his allies, and is at the mercy of Ambrosia. Put him out of his misery, right? That should end evil in the world, right? Wrong. Ambrosia finds out Murder Makes You Crazy, and starts killing her own party if she does that. Nope, the best ending is actually ignoring him entirely and letting him die slowly and painfully, while you have a quiet country life.
Strangled by the Red String: Lampshaded. One of the second characters his some reincarnation issues to deal with, and is doomed to end up with one of the others.
That One Sidequest: Some of the sidequests are fairly easy to complete (the romance one, most of the ultimate weapons). The sidequest to get all the treasures (you get a reward if you do) in either game is obnoxiously time-consuming (though not outright difficult in the first game), but in the Playable Epilogue, the chests are for the most part in different places, some inside mazes, while others involving involving complex puzzles (the worst of which is probably an extended music puzzle). You get the real treasure the first time (either game) you get all treasure, and the second time you do it, it's just a rare equip, so it's better if you figure it out the first time.
The bounty hunt is not terribly easy either. Most of the enemies can just fall in a few hits. Good luck killing the final one, though.
Why Would Anyone Take Him Back?: Possible, the main lover interest ditches in the middle of a trip to another dimension. Honestly, here the party depended on him to transcend dimensions, and he bails?!?
