Wow - Unreal Engine 3 for FREE for commercial use for indies

OK, this falls into the “very big news” category - Epic have just announced that the Unreal Engine is now free to use for indie developers - presumably including Machinima creators. That’s very big indeed, since it’s been used for commercial Machinima already.

Anyone know how much modding the engine requires before it’s Machinima-ready, if any?
