Lets star with the alternate universe scenario:
1.Scenario : SEGA would have been acquired by Microsoft, and the online capability still ruled by Microsoft, The Dreamcast may have been close to PS2 in term of sales.
2.Scenario : Another big player would have been competed on the console market like Apple, Nokia (at that time Nokia it's still on good condition). Microsoft would still made another middle ware (OS and direct X for console like what they did with Windows ME for Dreamcast)
