whats the one PS4 game i should get at launch?

Few games getting a lot of hype these days and also have some great comments from people who have previewed them. Games like Infamous second son would be more suitable if you are looking for single player action game however for multiplayer capable action game you should go with Knack or Watch Dogs. For shooter games Killzone shadowfall or Battlefield 4 would be more suitable.

Here are some more best games and their details which are available for PS4.

I don't know how i answered the wrong question.

My apologies!

But I will answer yours.

I recommend you buy KillZone. Guerrilla studios is an amazing developer and they makes top notch games.

You won't be disappointed with the quality.

It's also a Sony exclusive game, so it will have better integration with the Ps4, making it a great first game for your first Ps4.

Infamous second son looks good, but I don't recommend it, they got rid of Cole, and it will be hard to get comfortable with the new character.

Watch Dogs just got pushed back until 2014, so DO NOT bother. You won't have a game for a while if you get this.

I would advise you to get a PS Plus subscription now if you don't have one currently. If you have it, you will get Drive Club free. You'll be able to download it as soon as your PS4 is set up.

There are also a few good indie titles for free during the following months after PS4 launch.

Infamous The second son and KillZone Shadow Fall those are the awesome most game will be played in the firsts months of PS4 Release...
