Van Dyke pointed to a recent addition in War of the Roses, an online medieval battle game that he oversees. "Obviously we've added controller support [to War of the Roses], there's a proof-of-concept that definitely works." Of course, this doesn't necessarily mean War of the Roses is coming to PS4 – in fact, Van Dyke said Paradox still isn't sure what exactly it wants to do on PS4 yet.
"We first need to make sure we can get the game running on the hardware, but the hardware is much more easier to work with than it was previously when I was at DICE on Battlefield, where there were struggles with Sony's hardware – especially the way they allocated memory. They've eliminated a lot of these hurdles [on PS4] and x86 makes it much more plausible that we can do it."
For now, "it's definitely a realistic possibility and something we'd like to happen, but we're not entirely sure we can deliver on that." He said it's a bit of an inverse scenario for Paradox, where the developer wants to ensure its PS4 game isn't interpreted as "a cheap PC port on console."
