After Microsoft releases the next service pack for Windows XP we Mac users will get Virtual PC 7. This update will reportedly feature G5 compatibility and graphics hardware acceleration. If performance is good enough to play two-year old PC games this could affect the Mac games market. Ports would have to be based on new games because the older PC titles could be emulated with Virtual PC. Of course not everyone will buy a G5 and this software but two years from now publishers would be a lot more particular about what games they make OS X native. The only old-game ports that get made would be targeted at people who do not have Virtual PC. I think that most Mac-gamers will buy this software if performance is as good as promised. Personally I would want it so that I could play all the budget titles that are sold in games-stores, like Half Life.
