I'm not sure what you mean by that, but having made a complex game in CC with over 10,000 events, 500 objects and thousands of animation frames, I can state with some authority that my attempt to make something complex with CC didn't work well at all and CC is not reliably up to the challenge of making a large complex game. CC is barely, barely able to manage loot pursuit which is actually a medium to small game, and yet it takes 10 minutes to load the battle event sheet, 7 seconds of waiting for every single edit made to that event sheet, 30 minutes to undo or delete an object, 5 minutes to preview, there are events I can't move or edit without crashing the editor and I have to repeatedly close and restart the program when using the animation editor to keep memory leaks from crashing the program, not to mention all the instability caused by trying to do things like delete family variables or such keeping me from reworking the code.
Wow, that's pretty bad. Can I ask some questions about your project? How many layouts did you have and how much vram did you use? How many levels were in your game? How big was your file before it started acting up?
