The Purple Pawn website has posted a PDF of their 2010 Game Industry Survey.
From their website:
Purple Pawn has conducted a survey of over 7,000 companies around the world who made money from analog, tabletop games. You can download the 14 page report for free here [PDF].
Of the companies surveyed, those that did not close reported good results, with 85% reporting that they had done at least as well or better in 2010 than they had done in 2009.
Single-game game companies (sggc’s) make a significant portion of publishers. Sggc’s are eager to get the news out about their products, but likely to not actively build relationships, maintain an accurate website, respond to emails, and ultimately survive more than a year or two.
