Limbo was the best-selling game released as part of Microsoft's Summer of Arcade, and by a considerable distance too, Microsoft Games Studios VP Phil Spencer has revealed.
The sales info was used by Spencer to back up claims that Xbox LIVE Arcade is home to a diverse range of title.
"Our number one Summer of Arcade game is Limbo," said Spencer, "by a long stretch."
"I think there was a time when LIVE Arcade was about IP that people knew," he added, acknowledging that this will always be important.
"It's changing though," he said. "I really think coming out of Braid, Shadow Complex, Limbo ... that it's changing a little bit. We see that in the market, that it's becoming less about iconic IP that people know and it's becoming more diverse."
