The game industry has its share of myths.

1. Units sold is usually meaningless. I turned down an offer to sell a million units of Demigod because they would have been sold at less than $1 per unit.  So if you see someone talking about units sold, take it for a grain of salt (incidentally, every copy of Sins of a Solar Empire is a full blown copy).
2. What gets talked about by the media has little to do with how successful the title is. You’d think the world was dominated by first person shooters. Ask Walmart or Best Buy what they think of first person shooters.  Strategy games sell better but tend to be treated as second-class citizens to first person shooters.
3. Piracy is a joke. Freaking out about piracy is what executives who don’t actually play games do. Piracy is real. Lots of people play pirated games. But the % of them who would have purchased the game is nil. Some genres attract pirates more than others (See first person shooter item above).
