So yeah, the next Unreal Tournament game, called 'Unreal Tournament' to avoid potential confusion (yes, it is the one running Unreal Engine 4) will be competely free of charge or any sort of microtransactions, with mod support and best of all, croudsourced - that's right, if I understood what's been said on the stream correctly, UT fans will be able to directly influence development of the new game.

It seems that the team expects the bulk of money to come from licensing the engine, and there seem to be plans to make monetization of mods possible for content creators.

All the streams, hope those are the correct ones, didn't bother to check.

I think the term preferred on this forum is Ninjad.

Even having seen the topic it took me a while to find it using the abominable search function.
