the sad thing is the new WED seemed to be a good decision to sigh new life into the engine, but it was announced 3 years ago, and since May 2013 no news about it (still stays on 75%). missing its release could lead to the current bad state... but you have there MapBuilder Editor too!
but the missing updates and bug-fixes is a pain and means a high risk to start a new project (I have been brave enough to do it).
imo the pro edition is still a capable engine, and the commercial is fine for smaller scale games, but definitely very overpriced with the current editor set, in spite of its flexibility.
