Get:
The Binding of Isaac if you've never played any of them.
Snake Pass if you aren't a casual.
Shovel Knight Treasure Trove.
Puyo Tetris if you like either Puyo or Tetris.
Don't get :
1-2 Switch unless you are easily amused by 20 second mini games or have a very small attention span.
KAMINO is super awesome, and I normally don't look back but since I've totally forgotten Blaster Master, and the look and gameplay is updated I've been having some fun as if it were new to me.
