I just arranged to buy a ps4 from a friend so looks like Ill have one way ahead of when I expected to buy one.
Sweet. A quick launch guide based off my experience so far!:
Resogun is the best launch game imo. So much addicting fun, great co-op too.
Contrast is unique but may bore you (I personally like it, great atmosphere).
2k is great, bar a few problems. Best sport game available this launch with FIFA probably close behind.
BF4 runs and plays amazingly. But most of the maps suck. And I don't find it fun to play without friends. Single player gets boring after a while, but it's a good showcase for the game.
Killzone looks amazing. What I've played from the single player was pretty dull. But man the multiplayer, steals the show, I like it better with Battlefield 4s.
That's all I've played. I plan on picking up Lego Marvel this weekend cause the PS3 demo was fun as hell and it's a great couch co-op. I heard it's great on PS4 so why not?
