Despite the fact that Microsoft is making a concerted effort with Xbox and Windows 10 to establish its own gaming platform in the PC space, it doesn't wish to compete with Steam.
"We are not intending to compete with Steam," Microsoft senior director for PC gaming Kevin Unangst told PC Gamer at Gamescom. "If anything, we want Steam to be even more successful – they’ve done great things for PC gamers in terms of having a single store."
According to Unangst, Microsoft aims to attract more and more PC gamers to its own marketplace in addition to Valve's online platform. "Over time do we want more developers to come over to our store and offer it in addition to Steam? Absolutely. Is competition good for people? Absolutely. But our goal right now isn’t to do anything else other than support Steam and help it run great on Windows 10."
