Every game, even if it is multiplatform, is usually built with one platform in mind- the lead platform, so to speak. And each generation, that platform happens to be the console that is easiest to develop for, or the console that has the widest reach (more often than not, those two factors coincide).
So really, it shouldn’t come as a surprise to anybody that Avalanche Studios’ great looking Just Cause 3 was built with the PlayStation 4 in mind- the developers confirmed that to VG247 Italy today in an interview at Gamescom.
As they were quick to point out, however, this does not mean that the Xbox One or PC were afterthoughts- but just that the target spec for the game was the PlayStation 4, with appropriate adjustments being made to it to make sure it runs fine on the Xbox One and PC as well.
I mean, most games are built with the PS4 in mind these days, so that’s not really much of a shock. Still, it’s not often that a developer outright admits it, so this was an interesting admission, to say the least.
