In fact if the numbers we see in the industry are correct, distressingly few of them have discovered games as yet. That doesn't mean they won't. While Mark is an inveterate gamer, Suellen didn't buy a computer game until she had her first computer for a couple of years. We are just now reaching that stage with the first iMacs. The size of the potential market is only one thing that PC companies look at when they agree to have their games ported to the Macintosh.
Maintenance costs are a sore point on both sides.
Increasingly, PC games are coming out that are drastically and repeatedly updated. This may or may not be good for the gaming industry as a whole, but it is a disaster for port maintenance. A typical contract will include the port and any Mac-specific maintenance such as bug fixes, but there is not usually a provision for updating. Several people have intimated to us that the answer is to insist on better contracts that include updating. Insistence on an update clause can cause people to run screaming from the room.
