You are fucking kidding right?
Rule of Rose was absolutely Shit,
Terrible Dialogue,
Shitty controls.
Loading screens every 5 seconds.
It was like they pounded it out and hoped the controversy would sell the game on its own.
I never actually played it (I did find a copy of it recently but it was $50 and I don't have a working PS2 so fuck it) but I did watch a playthrough on youtube out of curiosity and it felt like it had the potential to be a really good game but just came out
really really bad.
There are a lot of 3DO games that are pretty unknown but really good. Guardian War and Kingdom: The Far Reaches (which was recently rereleased as a DVD game called Thayer's Quest, which confused me because it seems like the 3DO version is the only one where the main character's name is Lathan and not Thayer) come to mind.
Guardian War was a tactical RPG that wasn't too fancy but for some reason was really fun despite being map after map of ridiculous dungeons. The reason they were ridiculous was because the scenery was like...really blurry PHOTOGRAPHS with low-res 3D models for the monsters and characters. This screenshot explains it best:

Still, I found it to be very fun and addictive once you got past (or embraced) the silly graphics and the way the Goddess would say "Danger....DANGER" when you got into battle.
Kingdom: The Far Reaches was basically an interactive fantasy cartoon. Except it was like a point and click adventure game instead of a "hit the buttons at the exact right moment" game like Dragon's Lair or other animated games from the time. Basically there was a wizard who would make scrolls for you, and he had three or so different types. You'd tell him what kind to work on, and I think you only got the next one after you used the one you had. Then it was a matter of using the scrolls and other items you had at the right time and right place. You basically chose different locations on a map, but you had to be careful because if you went to an area before you had the right item you'd get killed. It's not overly complicated though, and it's pretty charming. One really weird memory I have of this game is going into a place that sold various car audio equipment and they had a death scene from this game as the demo for a car DVD player they were selling. I don't know if some company had this footage laying around or some nerd used it as a joke, but it took me a long time to figure out where I had seen that video before until I realized that it was from this game. It was basically the main character being surrounded by skeletons in or near a bog, or something like that. I don't really remember it very well anymore!
