Cosmetic Award/Playing With

Basic Trope: A reward that serves no other purpose than to be a proof of an achievement.

Straight: In the action RPG game, Chronicles of Troperia, Alice and her group of adventurers can defeat a number of progressively difficult Bonus Bosses, culminating in Quazarx, the Dimension Lord, which is the hardest boss on the game. For each one of those victories, they get cool statue built on the capital city... Which only serves for decoration.
Exaggerated:
- In Chronicles of Troperia, after clearing the Bonus Dungeon, defeating That One Boss, fullfilling each one of the citizens' requests, unlocking all the ultimate weapons, (some via a series of contrived interchange sequences) catching at least one of each fish' species in the world, taking a photograph of every single monster in the game, (including those annoying one-shot-chance ones) AND collecting all the 500 moon pearls; you reward is... A different title screen. You can scream now.
- The entire game consists of nothing except achievements. Anything you can do will result in getting an achievement.
Justified: Quazarx, and all the lesser Dimension Lords, intentionally rigged their fortresses and material possessions for them to vanish from this plane of existence, just in case someone managed to defeat them, in order to prevent said individual of gaining even a fraction of their power. So, no reward for you besides the praise of people. (And maybe some medals!)
Inverted: Defeating the Bonus Boss on Chronicles of Troperia grants a reward that greatly alters the mechanics of the game up to that point. For example: The ability to fly when, so far, you have lacked the ability to jump!
Subverted:
- Defeating Quazarx grants Alice the title of "Great Dimensional Champion", which at first seems useless until you notice the merchants have started to offer a hefty discount on all their services and products. Besides, you also gain access to a secret area where you can get awesome (and previously rare) items and equipment.
- After winning the "Champion's Tournament" mid-way through the game, you obtain a shining trophy to decorate Alice's home. However, near the end of the game you met with Armax, the Ultimate Blacksmith, which offers you to create Alice's ultimate weapon if you can get a chunck of Troperium for him to forge it. And fortunately for you, the trophy turned out to be made of it.
- All those trophies appeared to just clutter up Alice's house, but they're all made of metal and you can smelt and craft them into a decent set of armour.
Double Subverted: After winning the "Champion's Tournament" mid-way through the game, you obtain a shining trophy to decorate Alice's home. However, if you interact with said Trophy, it turns to be a portal to a pocket dimension where all your starting weapons get upgraded to Immaterial Weapons, which aside of looking incredibly cool and glowing with a ghostly light... Don't do anything special, they are basically a cosmetical upgrade of your starting weapons.
Parodied: After defeating Quazarx in what's possibly the most epic battle on the entire game, the dreaded Dimension Lord himself recognizes your superior abilities by giving you what is (according to him) the most prized award in the entire universe: An autographed photograph of him with an incredibly sappy dedicatory and a nice frame.
Deconstructed: ???
Reconstructed: Bragging Rights Reward
Zig Zagged: ???
Averted: In Chronicles of Troperia, every significant Sidequest yields a substantial and helpful in-game reward, no exceptions.
Enforced: In the XBo- Erh, I mean: Z-Prism 720 gaming console, ~~Achievements~~ Milestones are actually a required feature for any released game, so the developers have to include them aside the fact that some of them might yield an actual in-game beneficial reward.
Lampshaded: "What?! Did I almost killed myself back there in the Dimension of Infinite Pain and Despair only to get a lousy medal out of it? I demand a compesation!"

Quazarx: "Congratulations great warrior! And now, as a prize for defeating me... You get nothing! You lose! Good day sir! ... Ha ha ha! Just kidding: Take this medal as a token of my respect."

Invoked: Unfortunately for the king of Troperia, the war has greatly weakened his economical and military force, so it's impossible for him to grant Alice and her group a prize worthy of them, so the only thing he can do to honor their deeds is to try to immortalize their names in history. hence, the construction of the statues for them and their new Champion titles.
Defied: After one too many rewardless Bonus Boss battles, Alice finally snaps and she threatens the King of Troperia with the total annihilation of his kingdom if he doesn't grants her a worthy prize. After all, if her group slayed slay Quazarx, then burning a dying kingdom to the ground wouldn't be too difficult for them.
Discussed:

Alice: I'd love if once, at least just once, we could get an awesome reward after defeating yet another of those annoying Dimension Lords.

Bruce: We are heroes Alice! We don't do what we do for the fame, fortune nor the rewards, we do it to make the world a better place. And for each Dimension Lord defeated, I'm sure we are releasing a lot of people from a life of undeserved suffering.

Alice: Darn it, I think you're right! Sorry about that Bruce, I think I was being selfish.

Bruce: No problem. Besides, we don't necessarily go empty handed after all. Just look at the kickass statue of me they carved!

Conversed: "And what's your reward after defeating the most difficult boss the game? A new weapon? A secret area? A substantial power-up? No: A photograph of the game's heroine on lingerie. Seriously: What the hell?!"
Played for laugh: You gain achievements for ridiculous things: for moving to the right, for moving to the left, for not even touching the controler...
