Photon or SmartFox for Unity4?

Hi,

I plan to create some kind of MMO with SmartFox or Photon.

There is a high probability that my choice will come down to either SmartFox or Photon.

My question ist: does one of them (or do both) support Unity 4?

Thanks

I can verify Photon supports Unity 4.
The Photon Server can be fully customized in C# for MMOs or any other game genre.
No matter which produce you will use: For mobiles, you need a respective Pro license for Unity (iOS or Android). Otherwise “Free” is fine.
