Are people even reading the OP?

The OP isnt asking for Multiplayer game modes, not asking for modifications to the files.

They're asking for a film editor for the online world.

Yes you can dat mod, but its not the same, you cant empty Uldah, you cant modify individual file animations and its very difficult and tedious to get correct dat modding work with the correct setup and material, you also have non to very limited camera control and cannot edit lighting.

Read the OP before posting haha. This would be ace, but bare in mind they've been working on it 7 years and its in release beta now, so if SE were to say yes, it would not be for many years and be a lot of work.

As for Lux_Rayna i dont know what you mean by only works in Single Player, do you not watch Machinima? Its a freaking huge community and pretty much all with Multiplayer games, mainly FPS. SP is limited because of lack of NPC control, multiplayer its a blank slate with all NPCs undercontrol.
