My social game (for the last 3 consecutive months) has brought in about $8000 - $10,000 a month. Pretty consistently averaging about $300 a day. Generally spend about 4 hours a month on it total. To note: The developer I work with spends much more time on it than I do; but it is not a focus / priority for either of us. It took about 18 months to get it to this point. It probably got to break even in roughly 5-6 months.
