N comes before Z in the alphabet, and you must always AuthN before you can AuthZ. Easy mnemonic.

AuthN is: I claim to be dreadgoat, but how can I prove it? (login, password, mfa)
AuthZ is: Now that you know I am dreadgoat, do I have permission to post this comment? (access control, roles, attributes)

I’d say it’s between Witcher 3 or Dead Island 2, and comes down to what you want.

Witcher 3 is going to be an epic story-driven experience. Great writing and quest design, great RPG elements, but the moment-to-moment gameplay is beginning to show it’s age, and the combat has always been a bit of a weak point.

Dead Island 2 is more of a turn-your-brain-off-and-do-dumb-stuff experience. You aren’t going to be wowed by anything in particular, but you’ll have a very fun time mutilating zombies in hilarious ways. It’s overall less impressive than Witcher 3, but it’s also more modern and the better choice if you want something more casual.
