Defcon, Darwinia and Multiwinia devs, Introversion, say that it will probably not work with Microsoft again via XBLA.
“Do we regret working with Microsoft?” said Introversion’s Mark Morris, speaking at GDC. “No, but it’s unlikely we’ll work with them again … they make you work harder on the production value, but they don’t back it up with sales.”
Introversion had release editions of Darwinia and Multiwinia via Xbox Live Arcade, “XBLA were good to us and put us in the deal of the week, but it had no impact. Steam promotion was an order of magnitude better.”
Well, that seems to be that then.
