I'm thinking about getting a PS4 with some return money.  Help justify me getting one because I've been mostly playing local multiplayer on consoles these days.  My single player play has been reserved for PC and older consoles and I'm only willing to buy a console with local multi-player, especially when consoles have pretty much become simplified PC's.  Please help.

Borderlands: The Handsome Collection which grants you two long and fun games with up to 4 player offline co-op.

Diablo 3 with 4 player offline co-op.

Resident Evil: Revelations 2 with 2 player offline co-op.

Minecraft with 4 player offline co-op.

Rayman Legends with 4 player offline co-op.

Guacamelee! with 2 player offline co-op.

Geometry Wars 3: Dimensions with 2 player offline co-op.

Injustice: God Among Us (but this one's a fighting game)

Little Big Planet 3 with 2 player offline co-op.

Knack with 2 player offline co-op.

Thank you.  I'm really interested in Rayman Legends and Geometry Wars 3 in particular.

well from the games i currently have

guilty gear xrd sign and lbp 3 are pretty fun for multiple local players

Only thing me and my roommate play is Injustice, but if you can't get into fighting games, you might not get into this either.

Towerfall for local... amazing good.

I'm not anti-fighting games. Injustice seems neat but forgive me for not being very excited for a last gen game.

Metal Slug 3, Helldivers, Towerfall Ascension, sportsfriends, Dead Nation

And Knack. 

Lara Croft and the Temple of Osiris
