what i need to know before a create a game

hi everyone im just trying to create a game but every time i give up beacuse i dont know what to do so my question is what i need to know before a create a game

You need too know how hard it would be. How long it would take. And how fun it would be. You should try and figure those out. Now when you do what you need to know is what can you script and what can you do. Then add on to what you can do with things you ask on this site. And if you keep on building onto what you know you should do good. Its what i did. I knew little and slowly built onto what i knew and became pretty good.
