The Xbox boss has made the vow following the news that Street Fighter V will only release on PS4 and PC.
Spencer said on Twitter, “Business deals happen. We won’t do all of them.”
Spencer the referenced Killer Instinct, “When we have a 1st party franchise in a genre I’d rather invest in ours.”
“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. Love the idea of game franchise bartering, I’ll work on making amends for Street Fighter.
“I appreciate the competition, they do good work. I just focus on us and like you say I think that makes us better.”
Finishing, Spencer complimented Sony on its PlayStation Experience event at the weekend.
“PSX was a nice event, good way for Sony to celebrate 20 years,” he added. “I watched, it was well done. I feel good about 2015 for Xbox.”
