Sony announced PlayStation Now, it's streaming gaming service. This was brought up last year at E3, though seems to be coming together quicker than expected. PS4, PS3, Vita will be supported, and they're planning to expand to "other internet connected to devices"; TV, tables and phones are mentioned but the ETA is more uncertain.
They'll start the service in beta in January and aim for release in summer. It'll only be PS3 games at launch; they wouldn't talk about older games. They were demoing first party games; it's unclear if that means it'll only be those games. You'll be able to rent games or subscribe to the service entirely, but no prices were mentioned. They did not say if PS+ would be required. Performance at CES was good, but that's obviously a very controlled environment. This sounds promising but there's a lot more that needs to be known.
Even though I am pretty awful at it so far I have been addicted to Don't Starve the last couple days. My record is like 15 days survived so far and I have unlocked three new characters.
What's so great about the game is that you just continue to learn and apply things even though you start all over each time. When I have died I never get mad at the game because it is always due to some stupid decision I made. Highly recommended- especially since it's free!
Major Nelson's not posting the DLC and digital content for the week, so this list is surely incomplete. Feel free to chime in with whatever major things I'm missing. They converted from MSP to actual moneys this week.
