I played Bayonetta 1 on the Xbox, and had a really good time with it. I also watched the Bayonetta anime which does a great job at refreshing the story of 1 without having to play through it all over again.
I started playing number 2, but only got as far as the 2nd or 3rd level. Not that I did not enjoy it, but I think I was playing some other games at the time. I have been meaning to play that for awhile now.
As for Xenoblade Chronicles X, I highly suggest you download the 4 DLC packs available in the eShop before you play. Also, you should know that this games has 100's of hours of gameplay. I have only put about 40 hours into it so far, and am 2 tiny missions away from getting my first Skell (aka Mech). Hopefully by the end of today I will have it

(NOTE: You can get the skell after about 20 or so hours, but I have been taking on as many side missions as I can before I progress with the story missions... which gives me some pretty helpful bonuses this early into the game)
Well yeah... I am basically addicted to Xenoblade Chronicles X at the moment. It is hard as hell to put the game down and go to bed at night when I am playing. I just want to keep progressing... but it helps that the Wii U's Gamepad dies out, so basically I have to stop playing at that point... which I usually end up playing for another half hour or so on the Pro Controller.
Also, this game is incredibly deep, and has a lot to keep you interested. Tons of customization, tons of missions, tons of enemies... just a ton of game in general. Plus... BEST GRAPHICS ON WII U PERIOD !!! Sometimes it easily looks like it could be on the PS4 or XB1.
[MENTION=3657]pinky[/MENTION] if you have questions about Bloodborne or Xenoblade Chronicles X... I would love to help you out any way I can
PS. HUGE NOTE for Xenoblade Chronicles X: You only get one save file (possibly per user), so make sure you choose the right name. As for appearance/voice/gender/etc... you can change all that after chapter 5 (about 10-20 hours or so into the game, depending on how you play) once you complete a special side mission.
