Do consoles count? If so, I've spent over $2000 collectively, on two PS4's, a 3DS, games, and accessories, for each. If just games, somewhere around. . . ~$500.
EDIT: As much as I can remember. . .
GTA V: $60
Dragon Age Inquisition: $60
Battlefield 4 and all DLC: ~$50
Diablo 3 Ultimate Evil Edition: $40
Pokemon Alpha Sapphire: $40
Monster Hunter 4: $40
Ark: Survival Evolved: $30
Super Smash Bros for 3DS: $40
Random mobile games like Baldur's Gate, Halo Spartan Assault, Final Fantasy, and the like: ~$50
Watch Dogs: $20
I know there are others I'm forgetting. A couple Steam purchases, and then a few PS Store games, I bought.
