Paradox wants to see its line-up of PS4 games, including Magicka 2, come to Xbox One.
During gamescom, the PC publisher announced that Runemaster and Hollowpoint would join Magicka 2 on PS4 as well as PC.
CEO Fredrik Wester said that it was Sony's persistence and Paradox's decision to focus on one console at a time that led to it choosing PS4 for the time being.
"We are absolutely [interested in Xbox]. I spoke to Microsoft this morning," he told Digital Spy in an interview after Paradox's gamescom press conference.
"We're interested in the Xbox One, it's just we wanted to start with one of the consoles, and Sony was a bit more aggressive in pursuing us and getting things together. They were a bit quicker.
"But with Microsoft, I'd love to be on Xbox One as well. Take a game like Magicka 2, it belongs on both the consoles - it maybe even belongs on the Wii U, I don't know. We'll see.
"Magicka has a huge following out there, so we're doing our best to meet the gamers wherever they want to play the game, because that's the decisive factor after all. Most of our gamers are PC gamers, but a lot of the people also play on console."
