PS4 - inFamous: Second Son
Wii U - Nothing, I bought at launch cause I knew my favorite games would come, but Pikmin 3 was my first major reason
3DS - The Legend of Zelda: Ocarina of Time 3D

Hmmmm in that case:

3DS for me was Virtues last Reward.One of the best storys of all time.

PS4 was none actually.My brothers were planning to buy one, and since i dont have alot of money, i seized the chance.But if i had to name one, most likely Persona 5.

WII U would be Mario Kart 8 and/or Bayonetta 2.God Bayonetta was so good.

And finally vita was for Persona 4 Golden(Again, just bought it because of my brothers)

WiiU and 3DS - Having Metroid and Zelda one day. Makes me sad
PS4 - No specific game, but games i can't buy on WiiU

I don't think I bought the console in mind for one game.

PS4- track record, Japanese
Xbox One; familiarity, tv, achievements, etc.
Wii U- kind of the biggest disappointment for me; really wanted a true Paper Mario, a real 3D Mario game, even some shitty Pokemon game would have been nice. Definitely my least played console.

3DS however, I bought knowing Pokemon would be on it, therefore, I did buy it with a certain game in mind.

Wii U- For Super Mario 3D World (and I knew that Smash and Kart were going to be released as well)

Vita- For P4 Golden (but sadly I don't have it anymore)

3DS- I got it at launch, not for anything in particular but it had BC and I had some DS games to play while I waited for the new stuff.

I'll end up getting a PS4 next year perhaps with P5 being the game that pushes me.

PS4: I bought it mainly to play bloodborne and multiplats. Also looking forward to TLOU and uncharted sequel.  Also I'm a trophy hunter and I prefer it over achievements.

XB1: Main reasons I would like to have one are for the new ip's coming next year like quantum break and scalebound. Couldn't care less about their existing franchises except Gears of War.

Wii U: main reasons I would like to have one are for SMM, Zelda U and Mario kart 8 but specifically for SMM. That game is the perfect game for those who grew up with nintendo.

I bought the Ps4 because im loyal to the Playstation brand.

The have always given me the best game experiences since the Ps1, with the greatest exclusives and the best features among the rest of the consoles.

I dont buy a console for a specific game.

Wii U - For Zelda and Super Mario 3D World. I also knew SSB and Mario Kart would be released for it eventually.

3DS - Obviously Pokemon, as well as Fire Emblem Awakening

PS4 - I want to get a PS4 mainly for Horizon Zero Dawn, Uncharted, and Persona 5

Wii U: Because of inevitable Zelda
3DS: Because of inevitable Zelda
PS4: Because of inevitable Uncharted
Vita: Uncharted: Golden Abyss

But really, it's many Nintendo and Sony exclusives that make me buy them. Zelda and Uncharted are just my favourite respective franchises from each company.

I've never heard of Vitrues Last Reward. I'll look into it.

Bayonetta 2 is miles better than the first. Seriously. It's fu**ing amazing.
