Most of the newbies like me dreaming about launching their own games. That’s my dream too. I decided to create a discussion about istatistics. Let’s share your experiences. Is there anyone that became succesful about launching their own games here ?
-How long it takes?

-Which one took more time,Programming or Creating assets ?
-which issues was the hardest parts?

There is so many young people like me in these forums. And people mostly answers like:it’s so hard,it’s take so long…ets. But I think we need more details than that. We need numbers.
