The problem I see is your approach. You seem to be basing your decisions on if something is free or not.
What type of gaming do you expect if that is your deal breaker
You want old games you can't play online? Then cop a Super NES nikka
Is the XB1 backwards compatible, of course not. The Xbox 360 is still selling like hotcakes, why cut into that profit NOW
BUT, they are working on making Xbox Live Arcade titles available. And they said they can stream XB360 games to XB1 if there is a demand for it.
The question becomes, is there? The answer is NO. People bytched about it last gen, then they made them compatible. Nobody gave a shyt. It makes some sense right now at launch, but by 2014 when you have title after title of next gen goodness. Backwards compatibility becomes an afterthought. You being a sony gamer, you are confused bruh. You should be asking sony to entertain you. To provide content for your NEW system.
Thats your gripe.
Finally, the free games. Kinect Sports Rivals Preseason (I'm #25 in the world
)
Killer Instinct gives you Jago for free, and you can play vs online or offline. All free
Project Spark drops in a week or two (Beta) so you can create games sort of like LBP, but way more advanced. Thats all I know of right now on the free front.
