Tokimeki Memorial (+ Girl's Side)
Those games are masterpieces. There be some whacky shit in those games.
It's a dating sim / school life simulator with so much WEIRD, AMAZING STUFF crammed into them.
I hate/love all the minigames in them. The stupid petting-touchy-feely-aspect in the Girl's Side games ("skinship") requires more precision than most rhythm games I played. It's creepy, yet, fascinating. Like watching a train wreck. "Would you like to practice skinship with your underage kid neighbour?" (aka, I can see why they never localized them.)
They are criminally overlooked because none of them ever got localized.
You can fight bears by the way.
They punch you with salmons.
If you romance the Yandere in Tokimeki Memorial 4, you will also have to take on this dude, straight from Silent Hill:
Fvck, I love Tokimeki Memorial.
