Some of Black Friday's best deals are still available, shop NOW before they're gone

If we may make some suggestions, our favorite from this collection is Super Smash Bros. Ultimate because it has a huge roster of every character from previous Smash games, and is adding new ones through DLC. Just don't anger your partner by spamming the same obnoxious move, alright? Another great one is Diablo 3 Eternal Collection, because there's no denying that slaughtering evil demon hordes for loot together is just a teensy bit romantic, d'aww!
