Kafel, as usual, is unrelentingly negative.
First of all, just to clear things up, I was contacted by Ars Technica out of the blue for my comment on the story. I was not whining or complaining, and you can see in the article I recognize XBLIG for what it is.
Second, even though Sequence is currently the 27th highest rated game in America, 16th in the UK, 10th in Canada, and around those slots in other countries, I literally get about 18 trials a day, less than two months after release. That is to say, among an install base of 47 million, 18 people try my game per day. (Around 8 of those buy it.)
XBLIG suffers from a lack of exposure. I don't begrudge the platform, but that statement is ineffably true.
