Which one should I get for christmas?

Only one

 

-bloodborne complete edition

-Bayonetta 2

-splatoon

-monster hunter 4 ultimate

-just cause 3

 

I was also thinking MGSV but I haven't played peace walker

Both Splatoon and MH4U are great games. If you're into online console shooters, I'd say go for Splatoon. If a massive handheld game is what you're interested in, MH4U is definitely the best choice.

What genre interests you most and what are you looking for; re-playability, fun, challenging, open-world, fighting?

These are all very different games.

- Bloodborne is great, but if you've never played a game in the Souls series before, it might take some getting used to.

- Bayonetta 2 I haven't played, but I heard is good. 

- Splatoon is very fun online shooter, but that is where most of the fun lies though, online.

- Monster Hunter is great; you can sink a lot of hours into it, but it can get a little same-y.

- Just Cause 3 is probably a lot of fun (2 was anyway). Expect a lot of explosions, hooking onto a helicopter then jumping off landing into an already moving car.

 

All in all, it really depends what kind of game you're into.

Depends. I'd personally have done a poll for this lol. But anyways my vote goes for bloodborne.

I'd say Bayonetta. It's definitely a must-play action game from the best action game producers, Platinum Games.

ahh the masters choice TRACK 3!

 

bloodborne or monster hunter

I haven't played any of the games you've mentioned, but the suggestion that I can most closely make for you is to get Bloodborne, since that game was created by the same people that made the Dark Souls games!  If you've played Dark Souls, I'm sure you'll like Bloodborne!
