Any Next Gen engine imho NEEDS CSG CAPABILITIES in order to feel complete. LE 2.0 has a terrain system that is updatable, but it isn't enough. If you want to blow a hole in a wall, or if you want to break things like trees (aka Crysis) or if you want to create "on-the-fly" props from the engine, you absolutely need CSG. This is the *LAST* feature that is missing from the Leadwerks engine that is forcing me not to spend 150 USD. Fast realtime CSG is imho the next step in all 3D engines, as it accompanies the physics capabilities (things blowing up into bits and pieces, for example) which will make more realistic visual experiences.
