History ArtificialStupidity / PartyGames

** In ''VideoGame/MarioPartySuperstars'', the AI will make baffling decisions even on [[HarderThanHard Master difficulty.]] While they may [[ComputersAreFast dominate]] in minigames; on the boards themselves, you'll have characters use the Chain Chomp Call to move Stars even while they're close to them, repeatedly pass up the opportunity to [[VideoGameStealing steal Stars from rivals]] when they have more than enough coins to do so, occasionally ''not'' choose the path to a Star despite having a high enough number to reach it (apparently prioritising buying things from a shop) and most bizarrely, use a Custom Dice Block to roll a specific number only to stop right in front of a Star or roll a number that makes them land on a Red Space or even a Bowser Space. A Custom Dice Block lets you choose a number so the AI is doing this ''deliberately.''

* Gene is a recurring AI in ''VideoGame/TheJackboxPartyPack'', and his performance in games that allow players to freely write/draw things is predictably poor. His twists in ''[[TwistingTheWords Survive The Internet]]'' are randomly selected pre-written phrases that [[NonSequitur rarely ever make sense]]. Want pity points? Better hope you're not his victim. Likewise, his inventions in ''Patently Stupid'' almost never connect to the prompt. While his bars in ''[[BattleRapping Mad Verse City]]'' are at least coherent and properly-rhymed, they're still extremely tame.

** Throughout the entire series, the computer seems to have only two levels of intelligence: "[[TheComputerIsACheatingBastard beyond human]]", or "IQ of negative eight". They will buy items for easy access to the Star, even if the cost of the item puts them below the coins needed for the Star. The computer will also use items to roll multiple dice blocks to get to the star when they don't have enough coins to buy a star. It gets worse on the investment boards like Windmillville in ''7'' and Koopa's Tycoon Town in ''8''. Most of the time, they will invest ''every single coin they have'', even if it's not necessary or if ''they can't actually become the top investor'', doing nothing but helping the other players. It makes it impossible for computers to invest on the building that is right next to it, unless they keep getting low rolls and winning minigames.
** ''8'' has King Boo's Haunted Hideaway, which is a randomly-generated map that changes each time you play it. The [=AI=] seems to not plan ahead at path forks, and it will choose a path even if it knows the next fork on that side has one path leading to a dead end and a Whomp blocking the other, and that it doesn't have enough coins to pay the Whomp's toll.

* In ''VideoGame/GetterLove!!'', while you're pitted against three AI-players in normal mode, you'll have an advantage of your own in this otherwise difficult game. For one thing, AI-players epically suck at mini-games, letting you win almost [[PunctuatedForEmphasis every. Single. Time!]] (Except for the whack-a-nerd game and the quiz game, the former which they're actually somewhat good at, the latter which requires you to understand what anyone says in the game.) Also, instead of using offensive cards strategically (like to ruin someone else's date and possibly prevent them from declaring their love to someone for that turn), they tend to just use them on whoever has the most flourishing relationship with their girl of choice. Sometimes, if they challenge someone to a mini-game and win, one of their options includes changing their name, which has no effect on the gameplay, and they'll actually choose this every now and then. Most egregiously, whenever you talk to one of your opponents, you actually have the option to ''give'' them an item card or memory-unlocking topic, for no gain of your own, which they'll do every once in a while. Really, what's the point of doing that, or even such an option being there?

** During the "Chilly Waters" video from LetsPlay/TheRunawayGuys, the AI (Wario in this case) makes even ''more'' stupid decisions. He passes by the star ''multiple times'' and at one point, he duels Jon for '''one coin''' (by using a Dueling Glove he bought for 10 coins). Jon actually questions if the game is broken because of all the dumb decisions. And again, ''this was on hard mode!'' [[FunnyBackgroundEvent While all this insanity is occurring,]] Tim describes a previous occurrence when he played ''Mario Party'' solo and the AI made mistakes as bad as Wario's '''[[UpToEleven every single turn.]]'''

** In the soccer minigame, the goalie of whoever won the first round will become completely useless in the second, being unable to block a single shot. The enemy team however, [[TheComputerIsACheatingBastard will be able to make shots from across the field]].

** One particular case of the HARD AI in the first game being incompetent is pointed out by LetsPlay/TheRunawayGuys when Peach, otherwise a luck-manipulating bastard on Hard, proceeds to get the [[https://www.youtube.com/watch?v=krC7HTp-H80&t=4m33s Ground Pound Coin Minigame]] and use a total of 9 ground pounds to find the 5 "correct" posts.[[note]]For those unable to watch the video, this is out of 12 posts, and all 12 of them were plainly revealed at the beginning of the minigame. The pattern went something like "pound sharp post, pound 'correct' post, repeat". It turns out that the AI is programmed to do this and does this regardless of difficulty, since there's always just enough time to win this way.[[/note]]

For one thing, AI-players epically suck at mini-games, letting you win almost every. Single. Time! (Except for the whack-a-nerd game and the quiz game, the former which they're actually somewhat good at, the latter which requires you to understand what anyone says in the game.)

* In ''VideoGame/ItadakiStreet'':

** In the game released in the west (Boom Street or Fortune Street depending on your region) Slime has a while slew of idiotic behaviors, and [[InvokedTrope intentionally so]], being the board game equivalent of a punching bag for new players. Apart from taking balanced trades with no eye on the long term, Slime will only ever buy 20 stocks when he visits the bank, and only ever invest 200G into his shops at a time, leading to him swimming in ready cash by game's end. For the uninitiated, these games assess your progress by net worth, and there are very few situations where it's not advantageous to spend all your cash on stocks and sell them piecemeal as required - in fact Slime's failure to do this is why he often ends up lagging behind other training AIs.

He passes by the star ''multiple times'' and at one point, he duels Jon for '''one coin''' (by using a Dueling Glove he bought for 10 coins).
