DLC Quest is a satirical Indie Game for PC, Mac, and Xbox LIVE Arcade that takes Downloadable Content to its logical extreme. In this game, everything needs to be purchased. Including things like "Pause" and "Walk left".Visit the game's homepage here.Naturally, in keeping with the parody of shameless consumerism in modern video games, there is a Mission Pack Sequel: Live Freemium or Die, which takes sends Player on an all-new quest to collect coins and spend them on even more DLC (oh, and save some villagers from a monster or something).
Chekhov's Gag: The horse armor. Not just a shout-out! It turns out your horse comes to the rescue in the final battle, and if it's not wearing the armor, the bad guy will easily kill it and then kill you.
Cliffhanger: When entering the boss room for first time, credits roll. Of course, you can buy the ending DLC pack.
DRM: Parodied in Live Freemium or Die, which apparently has an 'always online' requirement... meaning that the game freezes every so often. At one point the Big Bad takes advantage of this by kicking you off the server and deleting your account, meaning you have to wait for a free slot to appear and then create a new account... which, of course, costs coins.
Excuse Plot: Parodied. The opening cutscene shows you and a princess—helpful arrows will point out which is which—as she is kidnapped by a bad guy, also identified with a helpful arrow. Finally, the bad guy grabs the princess and runs away, and another arrow helpfully provides a label saying "Motivation".
Parodied further in that while this quest does exist, in practice the game is ultimately about you collecting coins so that you can get more DLC which enables you to collect more coins so you can get more DLC...
Everything's Deader with Zombies: One DLC is a zombie pack, described as "This really doesn't really fit, but our marketing department said every game needs zombies."
Fanservice: Mocked with the 5 coin swimsuit DLC that changes every single characters clothes for the rest of the game. (Everyone is an 8-bit sprite, including the player and the princess.)
Memetic Mutation: Rather viciously parodied in-universe with Link, the town 'comedian' in Live Freemium or Die, whose 'jokes' basically consist of witlessly regurgitating various pop culture and video game memes ("It gets a laugh, like, a third of the time."), much to Player's frustration whenever you interact with him. Once you've interacted with him enough times, you can buy DLC which results in him dying from being repeatedly shot with arrows.
Multiple Endings: There's a good ending if you bought the horse armor and a bad ending if you didn't.
Nice Hat: The top hat DLC. Yeah, its a waste of 5 coins, but you look so spiffy after buying it!
Only Sane Man: Player just wants to get on with his quest, but is continually exasperated by all the crippling DLC limitations, pointless Fetch Quests and complete morons he has to deal with.
Product Placement: Parodied. During the second game, BUY POP billboards appear everywhere (you can pay for making them go away, which just replaces them with advertising for the studio which made the game), and there is a POP ZONE - BROUGHT TO YOU BY POP area.
Random Encounters: Parodied. There's one random encounter, and it happens in a fixed place at a fixed time. When they said it was "Random", what they really meant was that the character you encounter is named "Random".
Real Is Brown: Parodied with the High Definition Next Gen Pack which does nothing but making everything brown and pale. It references the trope name in its flavor text.
The horse armor pack is a reference to The Elder Scrolls IV: Oblivion's infamous DLC of the same name, which cost a whopping $2.50 for a cosmetic upgrade and received a massive backlash from the fandom. In DLC Quest, the horse armor costs 250 coins and is the most expensive piece of DLC in the game. It's also necessary for the good ending.
Up to Eleven: The DLC practices. All in the name of Deconstruction of course.
Unwinnable by Mistake: Actually grinding at the grindstone manually without buying the DLC leaves you with some extra cash, which you can use to buy things other than the Double Jump Pack when it's needed to get enough coins to actually finish the game. Soon you will have no money to even buy the pack and be unable to access the ending.
Video Game Cruelty Potential: You get an awardment for killing all sheep and humans in the game, including the shopkeepers* which you can still talk to for DLC-related business. This becomes a plot point in Live Freemium or Die.
