I am also tossing in the vote for Disgaea 5, the game may look like a PS2 title, but there is an incredibly amount of depth and value to it. Definitely worth it.

There's also a lot of smaller and cheaper games, Shovel Knight and Blaster Master are both great additions.

Obviously you already have the best bang for your buck in Zelda: Breath of the Wild. And I won't lie, you probably won't need much else than this until you're done of it; and it's not because the other games suck, it's because Breath of the Wild is so damn great! There's been nothing quite like this game before, it is definitively phenomenal.

I played it a few hours yesterday, awesome game. I'm taking all my time to explore, the games just invites you to do it. Not in a rush with this one, I might play it for months without actually finish it 

I play in Snipperclips with my girl (she don't play games) and she likes it :) First try demo. Full game is the same, but with much more content.
