Xbox product director Aaron Greenberg has claimed that third party publishers "have struggled" on Wii - and that Xbox 360 has the "best development tools" of any console.
Greenberg also claimed that over 70 per cent of third party publishers were creating software for Project Natal - support that exists because these firms have "thrived" on Xbox 360.
"Over 70 per cent of third parties that are selling games today are actively making games for Project Natal," Greenberg told the April issue of Edge. "That's impressive for something so new, that doesn't even have an installed base yet.
"A couple of things play into that: People know we're a software company, we have the best tools and internal support; and second, people who buy Xbox 360 buy a lot of games. Third parties have really thrived on our platform.
"Look at Wii - while it's done really well, third parties have struggled, so we've left a lot of room for people to believe in the ecosystem, and Natal is a part of that."
