I really love the new Tomb Raider Editor by Monty and his team. I had thought of retiring after Lara's Day Out, but once I'd downloaded the new Editor and spent a little time with it I soon fell in love with it. You can never go back to the TRLE or the NGLE after using this Editor, it's awesome. This is a new area I'm working on in the first level.
Give me a week or three, I've just started building a brand new area. The geometry will take a week or two, then there's the texturing, then I'll start thinking about the gameplay.
