Judging from the initial list of titles for both Microsoft's Project Natal and Sony's as-yet unnamed motion control wand, Sony is looking to move first-party titles by catering to players who already own a PS3 and the titles that are being upgraded to be motion-control compatible, whereas Microsoft, with its partnership with top publishers like Activision Blizzard, Capcom, Konami and Sega, is looking to create must-own titles that will move consoles.
In the current environment, Microsoft's strategy is the right one. While the Wii was the only motion-control game in town, Nintendo could get away with having mostly shovelware titles with only a few games worth owning. Now that all the major players are getting involved, the list of motion-control titles offered by each platform really needs to be exceptional, and the third-party publishers Microsoft's lined up looks ready to make that happen.
