hi everyone, as a developer I have a question that what option should I use when upload the game for public.(name your own price or paid).

 please suggest me for my 1st game upload.

That depends on what you think will work for your game. Marketing is tricky. In my experience, pay-what-you-want games earn more money, because people can try them first, and even if they don't buy that makes the game more popular overall. They'll show it to friends, place it in collections and so on. Also people with money will often pay more than the minimum if they like it. But if you're trying to make a living from games and treat them like products to be sold then maybe that's not right for you.

The important thing is, you can change your mind at any time, and set or remove the minimum price as you like, and also the suggested price. So just try both ways.
