Sunset Overdrive, Gears of War, DKC Tropical Freeze, The Last Story, and Xenoblade.

I'd list X and SSB, but I'm buying a Wii U for those games and BC specifically. But for just one of those I wouldn't.

I'd probably play some games that are exclusives if they were no longer for Sony and M$, however, there is not one I am dying to play that I won't just because it's exclusive.

In the end though, I get enough games between 3DS and Wii U.

Gravity Rush and Soul Sacrifice. A few months ago, I would have included Persona 4G, but having access to a cheaper version on the PS3 makes that a hard sell, even if it is inferior feature-wise.

XBO: Sunset Overdrive, Titanfall
PS4: Infamous, The Order
Microsoft in general: Halo, Fable
Sony in general: The Last of Us, Uncharted, any of the countless RPGs they've gotten exclusive.

Don't do this to yourself. P4 is still a good game but its missing sooo much content from Golden that it might as well be another game. I wouldn't wish for my worst enemy to play vanilla P4 knowing that P4G is out.

@OP For myself it would probably be Forza.

Bayonetta 2

Despite the fact I get Nintendo consoles every-time, on that front I'd currently say Pokemon and 2D Mario for them.

From Microsoft's stables, Halo... - at its best its a nearly cartoony FPS and that is what I'd want. Once upon a time I would have said Halo and Fable but... the last two Fables mean I'd need some convincing to get another.

Sony seem to have a large number of them overall, which is why I'm thinking about getting a PS4 if I don't end up with a power-PC. I'm just kinda used to free online which is the only real barrier, but most of the PS4 games I'm curious about are single-player anyway.

Sunset Overdrive.

He's basically asking which exclusive games you'd buy if they were multi-plat. 

God of War, Killer Instinct, Sunset Overdrive, Journey.
