P3P was a fantastic remake. The visual novel style overhaul actually worked incredibly well for a handheld. I also enjoyed how the female felt like an entirely different character as opposed to a re-skin.
I'd give TWEWY a close second due to being one of the few DS games that actually utilized dual screen gameplay extremely well and came from Square Enix during a period where they rarely released quality titles.
Also where's Bowsers Inside Story?
