* Very, very bad in ''MagicTheGathering''. It's gotten to the point where "Magic is dead!" has essentially become MemeticMutation.
** This is the reaction of many fans to every release of a new ''MagicTheGathering'' set. Even a single card, to many, can spell the doom of the game - witness the reactions to Tarmogoyf, Remand, and Umezawa's Jitte, to name a few prominent examples. Keep in mind that a new set is released every three months; that each year brings a new block (meaning cards from the previous block are no longer relevant in block-format tournaments or drafting); and that Wizards of the Coast has made a Banned/Restricted list for cards that break the game too hard. Even when Wizards brings back old cards, fans will decry some choices as being The End of [=MtG=] - even though they didn't break the game the first time around.
*** In 2009, Wizards of the Coast have [[http://wizards.com/magic/magazine/article.aspx?x=mtg/daily/feature/42a updated]] the official rules to make the game more accessible to more casual players. [[ItsPopularNowItSucks You know what that means...]]
**** [[http://www.top8magic.com/2009/06/ruined-forever-the-magic-2010-rules-changes-by-zvi-mowshowitz/ Magic always has been, and always will be ruined forever. That's part of what makes it such a great game.]]
*** The joke/truism passed around [=MtG=] circles is that Wizards could include 100-dollar bills in every pack and ''people would complain they were folded wrong''.
* Chaos and Heroes ruined ''[[{{Yu-Gi-OhCardGame}} Yu-Gi-Oh!]]'' forever!!!!
** No the pyramid of light ruined the game forever!!!!
*** The kid's toy duel disc system ruined the game forever!!!
*** Synchro-monsters ruined the game FOREVER!!!
*** The newest ban list ruined the game FOREVER!!!
**** Wanna know why the above is mentioned? LIGHTLORDS RUINED THE GAME FOREVER!!!
**** UPPER DECK RUINED YU-GI-OH FOREVER!!!
**** Exceed Monsters will ruin the game forever!!!
***** The game was very nearly ruined by Xyz Monsters due to a ruling that allowed [[GameBreaker profound abuse]] of a certain card. The price of this particular card shot to nearly [[CrackIsCheaper $200]]. The mistake was noted, repealed and, ironically ruined the game for all those who had bought the cards instead- [[DoubleSubversion that is, until the playerbase realized that those very same cards were still insanely broken, and went on to dominate competitive play for the next year]].
* All the [[{{Noob}} donks]] have ruined {{poker}} FOREVER!!!!
** {{ESPN}} has ruined poker FOREVER!!!!
** Texas Hold'em has ruined poker forever.
* ''Champions of the Galaxy'' is a very small press game with a very...''dedicated'' and ''invested''...fanbase, many of whom have been playing for twenty years. A recent move from B&W cards to full colour has [[http://filsingergames.proboards.com/index.cgi?board=gwf&action=display&thread=5111 ruined it forever]].
* CardfightVanguard: Because this game's fanbase is heavily composed of former YuGiOhCardGame players who griped at the aforementioned volume of [[GameBreaker abusable combos]], they can be incredibly paranoid about any newly-revealed card being [[PowerCreep too good]]. Cue cries of "OMG GOLD PALADINS ARE GETTING TOO MUCH SUPPORT!" "OMG THAT'S BROKEN!" "WHY DO YOU DO THIS TO US?". Specific examples include:
** Radiant Lion, Platinum Ezel: at first, fans were enraged by this supposed game-breaker powering up all rear-guards. Then they realized how difficult it would be to meet the required conditions.
** Bad End Dragger: With the Spike Brothers already having an overkill combo, this card appeared to be making said combo even more obnoxiously unstoppable... Until you realize that Spike Brothers also happen to have poor defensive capabilities, and would need to hang in longer if they have any hope of lasting long enough to pull it off.
* Being a LongRunner, ''LegendOfTheFiveRings'' has seen a lot of these, both game-based and story-based.
** Any character death. Since LegendOfTheFiveRings is a {{Chanbara}} epic with LoadsAndLoadsOfCharacters and the storyline has spanned decades, this happens a LOT.
** Any time a new faction is introduced or an old faction is retired. Naga forever!
