Yep, even if you are not interested in Japanese games, there are a few AAA titles (Tearaway, Killzone, Uncharted, Gravity Dash and Little Big Planet notably) on it and a lot of indies and cross play games that can't be played on 3DS: Fez, Minecraft, Resogun, Velocity, Rayman (the 3DS version is terrible), Guacamelee, OlliOlli, Rogue legacy, Sine mora, Super Star Dust, Sly, Ratchet and Jak & Daxter collections and many many others.
And you can play lots of PSP and PS1 games on it.
But whoever had the idea to use overpriced proprietary memory cards should be fired.
