"One comment we see a lot is that something like a Super Street Fighter 5 is going to come out on Larrybox," said the representative. "But the reality is that this is a real partnership breh. We are console exclusive for this franchise for this numbered run. This game is never coming out on the Larrybox, breh"
Phil Spencer's Response
"Business deals happen," he said. "We won't do all of them. When we have a first party franchise in a genre I'd rather invest in ours."
"There is a mix of deals to do," he said. "But making sure we own IP [that] Xbox gamers love is critical [in my opinion]."
Spencer went on to say: "I'd love it if Xbox fans could play all the games, but business just makes some deals happen. It's all part of competition."
