Quote: "Can anyone name any decent games made with Unity that anyone has actually heard of? On PC? 360? iPhone?"
The commercial ones are:
The Global Conflicts games
GooBall
Cartoon Networks: Fusion Fall
Dukateers: Treacherous Treasure
WolfQuest

Quote: "Sounds like a pretty powerful engine, but seeing as they don't support C++ it's probably not going to be interesting to many developers."
From what I've seen, the engine itself is written in C++ and working with Unity you can either choose to use the scripting side, or you can choose to dive into the engines source code, or you can do both.
So it basically up to the person to decide which route they want to take. Kind of like Valve's Source engine, and id Software's Tech 4 engine.
