I was trying to jot down some points as to what are the usual problems faced by a developer before, during and after development so that I can research and find a plausible to solution to them. I mean, it is not simply to identify neither solve them easily, but identification of those things will give us a headstart to deal with them in some way. I am sure many of us have already overcome such troubles we had faced before, so sharing your insights will help newer developers who are facing the same. I am not specifying any particular thing because I want various types of problems on my plate so that I can work on them. I have my own list which I had experienced during development, but I will share it only towards the end adding how I solved it. I want to see if I missed out on anything else which others might have faced. What I gain from this is valuable insights. And it would not only help me but also other developers to cope with those. Those who have coped with those problems can share their advice also. So please share what is the most important problematic issue you had to face when you developed a game which is still not solved or required too much time/energy/money than it's worth.
