Sometimes, when you accidentally think too much about things, you come up with crazy ideas, like some cute games are really horribly horribly violent and ill, but damn are they cute! So, I didn't really order these, they're too cute to!
First up, Patapon. These little guys are so cute, they come in different colors and army types, they have their own tribal society in which they worship you. They play trumpet to a dancing tree, they play with a baby mountain, they all gather around the fire and discuss what they'll find at Earthend. Then they go out and kill things. Common hunting animals, boss creatures, and members of the evil Zigoton army. They use fire equipment, spears, music notes, swords, horses, arrows, axes, clubs and other stuff. Then they do it all to downright infectious beats that you provide that they all follow and can perform miracle dances. So much killing, so much cute!
Yep, the Pikmin series. It's sick in a similar way to Patapon, you control the pikmin, have them kill things, be killed, make more pikmin, fetch in-game product placements for your ship for arbitrary reasons and kill things. Ok, sure I could see the ones that attack you, but what about the Glutton's Kitchen boss in the second game? That thing doesn't even attack you, you just kill it because it has an item in it. And the pikmin themselves are just so cute, even the white ones which I sometimes sacrifice to the boss because the poison damages it.
And we can't forget the Advance Wars series! At least the first 3 before Days of Ruin attempted to make things more serious by not having over half the COs be teens who constantly joke with each other. Seriously, this is a war game! Anyone ever infantry spam? Imagine how sick that'd be IRL. How about in the 3rd game, Dual Strike, where some of the other COs demanded that you have a decidedly not mock battle with them to prove that they should join you. You already know these people from the last game, you're just wasting time now! About 3 or 4 weeks later they go "yep, you're good!". And then you take over cities, factories, force people to pay you taxes (more if you're Sasha) and yet conversations are often "OMG! Grit and Olaf are so cool! They're my idols!" "Colin! You're my little brother, treat me like a princess!" "I think we'll get along great, Jake!". Awkward Zombie has a great comic about this called "No Fighting in the War Room". But man, the characters all have infectious cute themes, kinda fun pointless banter, super power moves that are cool, and are all "relatable" teenagers (Orange Star is at the very least). Not to mention that all the graphics for the people are kinda cute, even the little infantry mech guys and the little guy who stands next to the rocket (he's my fav)!
Here's another must, Katamari series of course! The entire game is filled to the brim with infectious ear worms that are totally self obsessed with the game and even as everyone screams as you pick them up with their eventual fate to be crushed into stars, you can't help but smile when you pick up your first person. Virgo is one of the worst, the entire object is to pick up as many females as possible, so you'll get mermaids, little kids, female workers, older children, etc. and turn them all into a star! And then you can also destroy them into stardust, hehe. But the whole game reeks of it's own sort of cute absolutely everywhere. And man do I enjoy it.
Just look at this cover! It has a cute little golden monkey that always goes "ZAAKUU!!" and a pirate kid who likes eating chocolate. It's an old fashioned point and click puzzle game with charm bursting everywhere out of it, partly in cute design, partly in making decent use of the waggle. But there's a decent list of rather cruel things you do: turn goons into totems, annoy a baby dragon to no end to purposely anger its mother and make it breath fire for you, turn bats into umbrellas, centipedes into hacksaws, worms into straws, and frogs into bombs. You drug an entire tribe's celebration...soup? with some sort of sleeping powder so that you can go steal their treasure. What a jerk.
Eh, just pick one. You're constantly trapping adorable animals into small magical balls, forcing them to fight and stealing their freedom forever. Yeah, any given Pokemon will warm up to you (sometimes to evolve) and love you for forcing them to fight to the brink of death all the time for you. I find them kinda expendable and like most people trying to get a complete pokedex, I catch a Bidoof and shove it in the PC for all eternity. And then there's supposedly only 1 legendary that is somehow important to the world, so let's catch that too. And most people have a special "breeding ditto" that they shove all their other pokemon with into the "daycare center" and force it to do that sort of thing for as long as you want. Still majority of time is making them fight (pretty sure that's old news at this point though). I admit I'm a hopeless addict though, hehe.
Just a character here real quick, lookit the guy! Now look at him swallow enemies (even those larger than himself) into his infinite stomach and steal their powers. Or just plain eat them. It's a slightly more horrifying fate than being rolled into a katamari. No wonder he's such a force to be reckoned with in Brawl, he can even turn into stones right on top of people and try to smash them. And he's so cute and looks so huggable! And he actually looks good in pink.
