Then there's Wazdakka Gutzmek, an Ork Big Mek whose lifelong ambition is to built the most awesomest bike in the 'ooniverse. How awesome? Well, he used it to ram into the cockpit of a Titan and kill the people inside. For his next trick he'll try fitting it with a fully functional warp-drive, so that he can ride from one side of the galaxy to the other (and shoot anything that gets in the way)!
His bike has so many flashy gubbinz that it's one looted antigrav system from being a jetbike, has no less than three large guns that can all be fired at once (going by the wording in his entry), and the man himself has been depicted in art with a chainsaw claw.
Even on the mundane note, a boltgun (standard small arms) weighs about 7.5 kilograms and fires .75 caliber rounds. That's right, it weighs twice as much as a modern M16, has three times the barrel diameter, and fires armor piercing high-explosive rockets, and manages to have a 50% larger standard magazine to boot. It is amazing what players take in stride.
While it may not be as Egregious an example, the swords in this universe run on combustion engines, the tanks (designed by superhuman werewolfspace vikings) are powered by hydrocarbon-fission-fusion cells, and the space ships are powered by SLAVE LABOR.
The /tg/ board on 4chan has been seen discussing how to properly min-max Surtr. As in, the Norse fire giant destroying the world. That Surtr. Min-Maxing him.
The 3rd Edition Epic Level Handbook explicitly encouraged the Dungeonmaster to do this to the players with ridiculous and unfair challenges on the grounds that the players will have the resources to deal with them. How far can the Dwarven Defender swim through lava?
Paranoia. The fall damage chart goes up to orbital.
The questions in question are "how many consecutive character sheets must we hand out?" and "how large a pipe do we need for the inevitable hose job?"
Spirit Of The Century lets player characters pull off some ridiculous stunts to rise to the challenge, so long as you're willing to be creative and spend a fair number of Fate Points. Oh, and any game that is willing to include build-it-yourself gadgets and the potential to fight talking gorillas on the top of a Zeppelin is guaranteed to go Up to Eleven.
Dont Rest Your Head has the same mechanic that is slowly wearing you down and making you more powerful at the same time, pretty much guaranteeing you'll push a little further next time. By the late game (which can sneak up on you surprisingly quick) you're more powerful than the (possible) incarnation of Death. And, using the madness powers, by this point you have power that's so over the top you could call down the four Horsemen, or an army of ninjas, or make enough ants crawl out of your skin to consume the city. It gets pretty intense when you're creative.
FATAL. At any given point, you will be unable to believe it could possibly get any more complicated, poorly worded, and deeply broken in its attitude towards sexuality. And then you will turn the page and find a dildo that makes you give birth to another dildo. Brain Bleach may be necessary.
They brought this trend back in Innistrad, where there are TWO 13/13 creatures, Ludevic's Test Subject a blue 0/3 that transforms into a 13/13 if you pump enough mana into it before it dies, and Elbrus the Binding Blade, an artifact that becomes a 13/13 Demon.
It must be kept in mind that in that horror-themed block 13 was an important Arc Number, featured on many more popular cards about bad stuff (13 damage, which is a lot, temporary -13/-13 power and toughness to a creature, which is often lethal, 13 zombie tokens, and so on).
Unglued also contained the card(s) with the largest mana cost, the aforementioned B.F.M., whose 15 black mana symbols stretched across the entire top line of the card. Once again, Unhinged decided to top it with Gleemax, a card which costs 1,000,000 mana. Yes, that's one million mana. I hope you brought your Mox Lotus.
