Not much nostalgia for Jet Force Gemini, a Rare third person shooter where you adventure through missions, each having secret routes to find using guns/keys you slowly unlock. The game had a bit too much completionist vibe to get to finish it, but was exciting as a kid.
On the 3DS, I also liked Resident Evil: The Mercenaries 3D. Basically RE’s best arena mode expanded out with perks on a game you could play mobile, and online. I still hope to see more of that type of experience.
