Shadowrun/YMMV

• Darkness-Induced Audience Apathy: See the entry on that page for details. To sum up: 5th edition has been a never-ending, soul-wearying parade of disasters, apocalypses, and crises, to the point where pretty much every formerly stable element of the gameworld's society and culture is now fragmenting and some readers are honestly wondering if the metaplot is going to become a post-apocalypse game, with 5th edition being the buildup to some kind of world-devastating Final War.
  • As of this posting, Shadowrun has managed to make it to 6th edition without the collapse of human civilization... largely by quietly ignoring many of the plot hooks they'd raised in 5e and just pretending nothing had really happened there.
• Game Breaker/Elite Tweak: Third Edition has an Edge called "Connected" that, when taken for a vendor contact, allows you to buy from that contact at the list price or sell at the street price, which can be as much as three times more. Thus, taking that edge for two contacts (one to buy from, one to sell to) allows a player to get ridiculous amounts of money while the GM isn't paying attention.
  • The physical adept can become noticably broken if you use initiation to offset the Essence cost of cyberware.
  • The chemical DMSO. If you splash it on someone, it allows for other chemicals to be absorbed into the DMSO-coated skin. Additionally, armor has little to no effect, so if someone hits you you with it, you WILL be affected. The end result being that if you mix DMSO with poisonous drugs and load it into a squirt gun, you get a super soaker that deals one-hit kills. You can hear details about how this can affect a game environment in this video.
• Genius Bonus: The Crime Mall is a literal Black Market complex operating from the remains of an actually abandoned shopping mall in the Puyallup Barrens, dealing with goods that normally couldn't be found and/or purchased from regular merchants or are considerably beyond the reach of anybody who has a SIN. The real life Puyallup town has its origins stemming from Native American tribes who first settled there in around the 1830's and whose name literally means "the generous people" in their native dialect. It was only after 1877 that a European cartographer mapped the town and named it after the tribes who lived there.
• Germans Love Shadowrun
• They Just Didn't Care: prebuilt characters from the 4th Edition corebook. There is something wrong with every one of them. Barely any have a Fake SIN (basically an ID card required in all civilized areas), and that's just the beginning. The Technomancer? Gets -1 dice to Reaction and Agility tests because of being encumbered by worn armor (the "maximum armor" rule is stated in the same book, no less). Same goes for the Weapons Specialist from the More Dakka entry. She also doesn't have anything that would allow her to use that laundry list of guns more than once per turn (as opposed to other combat-oriented premades like the Street Samurai and the Gunslinger Adept). Drone Rigger? Has cybernetic eyes (with Image Link modification built in by default) and goggles with Image Link as the only modification. Even with no Min-Maxing, a player with experience in Point Build Systems would achieve better results.
