I already have a psp go so the backwards compatibility on Vita is useless to me I don't have any of the ds family so it would be new to me.

The games i like:

Ps vita

Teareway

Killzone mercenery

Persona 4 golden

Borderlands 2

Rayman

Olie olie

AC liberty

3ds

Legend of Zelda ocarina of time and majors mask

Mariokart 7

Monsters hunter

Kirby

Luigi's Mansion

Metroid

Lego hobbit

Pikmin hey

I can only pick one because of my mom and i can't make a mistake of choosing the bad handheld so what would you pick if you can only have one and with what handheld did you enjoy the most.(what handheld offers more fun)
