Entropy, thank you for your support
I think I did it the way you asked, but in addition to the errors below, I believe I need to change something in the GamePlayManager.py file. The following is the log
************LOG ERROR****************
Attempting to load scenario: LTK
Traceback (most recent call last):
  File "c:\sourceges\gesource\python/ges\GamePlayManager.py", line 46, in LoadScenario
    scenario = getattr( sys.modules[module], scenario_name )()
KeyError: 'GamePlay.LTK'
During handling of the above exception, another exception occurred:
