At long last "Halo 2" will soon be available to PC gamers, but there's a catch. Its only good on Microsoft's new operating system - Windows Vista. If Microsoft execs think that using "Halo 2" is going to motivate gamers to get their new software they're nuts.
PC gamers are a slightly different animal than console gamers. They have their own little niche of games and while the original "Halo" is certainly popular among PC owners, its not the must have game it is for Xbox owners. Combined with the fact that "Halo 2" came out 18 months ago (die-hard Master Chief followers surely already have it) and that Windows Vista will cost a few hundred dollars by itself and I don't really see this as a smart marketing technique.
"Halo" is a wonderful series with a great future and single-handedly put the Xbox on the map, but it sure looks like Microsoft might be leaning a little too much on its franchise defining game.
