UDK/CryEngine 3 Tool set comparison

Where I write about the features and usability of UDK and CryEngine 3's level editors. These are not tutorials, I'm merely telling what's nice and what's annoying on each side.

DISCLAIMER: Apart from the sentences where I'm blatantly giving my personal opinion, I'm usually stating facts. So don't feel offended if I talk bad about your favourite engine. Also, bear in mind that I don't have comprehensive knowledge of the engines (especially for CryEngine 3), so if I said that something cannot be done, although it can be, it most likely means I've missed the right tool/option/command. In that case, feel free to leave a comment to correct me. Otherwise, any comment along the lines of "I think this or that is better" will be moderated, unless it comes with appropriate argumentation.
