Ï myself have played AG's whole my life and I have always wanted to create a game of my own.
I'm just finishing tutorials of
Point&Click Development Kit http://www.adventure-creator.com/ and it doesn't seem too complicated when you put your heart on it with focus, and added boost of inspiration! I don't know if there are easier and better engines to create AG, but I stumbled upon this and so far looks good since I have zero experience in scripting.
I'll start with testing and such, trying different things so then I can put my 100% focus on game and story itself, rather than trying to learn mechanics and basics of creating it.
