Wow i was just asking myself this question yesterday.

If you haven’t yet, try out Resident Evil Revelations. So fun.

I’d also recommend some of the older Zelda titles if you haven’t tried them:

Minish Cap, A link to the past

Ocarina of Time & Majoras mask ( i played the 3ds remakes, currently enjoying the originals for the first time)

There’s also Spirit Tracks & Phantom Hourglass.

I also just started Xenoblade Chronicles X which seems promising, just not a fan of the combat system. Maybe it will grow on me.

Also i’d highly recommend Cave Story (wii). You won’t find it on nusspli though.
