Ps4 – Protect Playstation from Power outage and Surges

PS+ subscription comes "on top" of the usual (free) PSN subscription, you're not restricted to playing with members of either group of users by being a member of one group or the other (PS4 games can only be played online if you're a PS+ subscriber, though).

The games offered through PS+ "Instant Game Collection" are exactly the same as their "full priced" counterparts, meaning they have all of their features intact, including online play. If you got a game for free through PS+, you'll be able to play it as long as your PS+ subscription still hasn't expired; If you bought it with a PS+ discount, it's yours to keep forever.

One exception worth noting with PS+ is that a couple of free games offered have only their "single player" component included. These are "Uncharted 3" & "Starhawk". The online component for these games can be bought separately.

I always used mayo to get crayon off of things. Perhaps a little safer than putting water on the PS4, and with the side effect of making your PS4 more delicious. Just put the mayo on the crayon markings and let it sit for a few minutes. Should come off clean with a rag without a lot of effort.
