People aren’t here to make a game for you. If you have put in effort and have a specific problem, some are willing and glad to help. Posting asking what unity or any software is when a simple look at the site or google would have answered you, then saying you EXPECT us to help you is pretty presumptuous and rude. That’s why you received those responses.
i already used unity3d to make my first game and used it as my thesis proposal and got a huge success but the thing is i never asked how to begin… all what drove me is my passion to games and done it with no time… so use Google as u found this here and go download one of the many game examples unity has in the download section heard of youtube 2? use it for tutorial tc mate
its free but for android and iphone its not free you can buy android and iphone version from the unity store if you want tutorial you can get it from youtube but there is no vadios for android i do not know why
