You can use a VPN to download it (I tried it). Don't know if you can do anything more with it though.
So here are my first impressions:
- Credit card info is required.
- You can use an Xbox controller! You can use it in-game too.
- I tried Infamous 2 and God of War III. You can use any controller, no KB+M though (except for navigating the client).
- Audio quality is great, but the video quality is kinda meh. The bitrate is pretty low.
- Games that are 60fps run 60fps.
- Input lag is comparable to using remote play or Steam in-home streaming, so pretty decent.
- Games that require Sixaxis (like flower) are unplayable. Probably only playable with the new dongle.
Client looks interesting. It's basically like Netflix, except you can't search for games. You can click on a game to add it to your list or simply play it. You can only find games if you scroll through the categories or scroll all the way to the bottem where they are sorted by the first letter of their name.
This is what GoW III looks like:
I have 250 Mbit/s down and up, so take from that what you will.
