I figured they would launch at least one Star Wars game, since there were so many great ones released in that generation.
But I am surprised that not one SEGA game appeared at launch, given that they moved many of their popular franchises exclusively to the Xbox after they discontinued the Dreamcast- Crazy Taxi 3, Jet Set Radio Future, Shenmue 2, Panzer Dragoon Orta, even Sonic Heroes was going to be Xbox/Gamecube only before Sony made threats. I have a feeling some of these won't make it purely because of music licensing (the XBLA version of Crazy Taxi has a different soundtrack for this reason). Not that I've given up hope on them!
Also, am I the only one disappointed that Microsoft didn't include the dashboard in their emulator? I kinda miss the design. And the ambient sound effects... jk but they really should include them in the Xbox One dashboard as an option!
