Wheeew! I need to take a breather after that!
I'll more than likely hold off on MGS5 as I usually try to get Limited Edition versions of Kojima titles. I'll be getting it on PS4 though as I will for most offline, 3rd party titles.
[edit 3 more!]
Shin Megami Tensei X Fire Emblem (Nintendo Wii U)
Super Mario 3d World (Nintendo Wii U)
Bayonetta 2 (Nintendo Wii U)
...and 12 more bringing my grand total to 36. Stick a fork in me!
Pikmin 3 (Nintendo Wii U)
Tom Clancys The Division (PlayStation 4)
The Order 1886 (PlayStation 4)
Beyond: Two Souls Special Edition (PlayStation 3)
The Legend of Zelda: Windwaker HD (Nintendo Wii U)
Wonderful 101 (Nintendo Wii U)
Deep Down (PlayStation 4)
Driveclub (PlayStation 4)
Super Luigi U (Nintendo Wii U)
Gran Turismo 6 (PlayStation 3)
Splinter Cell Blacklist (PlayStation 4)
Final Fantasy XV (PlayStation 4)
I gotta say though, this is a killer deal with little to no risk for the buyer. Normally I wouldn't even consider this heafty of a pre-order purchase but I know that, in the space of a year to 16 months, I easily purchase this many games. I can always decide to return the ones that I'm not interested in as of launch.
Thank you Futureshop!
