Raven has a history of expanding id's tech and toolsets. Let's not be narrowminded eh?
After working with the Doom3 tech expansion for the better part of 4 months I'll tell ya that it's asset pipeline is 'way' more efficient, way cleaner, and the lighting system is so much simpler than what Source is 'right now'.
Not to take away from the power of the Source, as I've been learning it for the last 2 weeks and it's very powerful, but it's simply not as robust, and it certainly has a much clunkier asset pipeline than doom3. Doom3 needs one text file to control 1 asset, 1 lighting system for all geometry. Doom3 gives me less variables between my concepts and my final product, and a prettier final product at that imo.
I haven't seen what Raven has in store, but I'm already sold.
