Paper Mario Sticker Star Monster Hunter 3 Ultimate Luigi's Mansion Dark Moon Castlevannia: Mirror of Fate
The two longest lasting and probably best.
Luigis mansion is damn good.
I was thinking of getting PM instead of MH because I play on the regular 3ds and i dont want to buy the CPP
You don't need a CPP at all. You can use the directional pad, and the default virtual d-pad just as easily. I have well over 400 hours in MH and have never struggled without the cpp. The game literally has 3 alternatives to the CPP, you can use "the claw" and control it with the left D-pad, use the virtual D-pad for an imitation 2nd right side pad, or use the lock on center camera which always re-center the camera facing directly towards your target monster.
All of those options, including cpp are viable, but thinking the cpp is necessary is flat out wrong.
