I really enjoyed the video. I disagree about the engine being complicated to make a map for, but love it because anyone who has ever made a map can relate to the seemingly bullshit errors tool and the editing kit throws back at you.
Considering the engine dates back to 2001 it holds up really well in it's simplistic nature of the tag system. The editing kit came with plenty of documentation for making a map but not so much for other things like weapons and characters. There are a lot of nuances in working with the engine but it is relatively straight forward to work with.
Anyway great video, I really enjoyed the humor and want to see more like this!
