World map based games. I am interested to make similar game but I don’t know if unity3d is good for that. How much time to make something similar to first game, without any unity skill?
I know java, android sdk, etc. but never Unity3D

Sure it is. It’s good for just about anything you want to make.

How long it would take depends on a whole lot of things:

  1. How fast you learn.
  2. Resources you’re exposed to.
  3. Amount of people on your team.
  4. Time you have available per day to work on it.
  5. Your productivity skills.
  6. Whether you already know how to program.
  7. Existing familiarity with any of the number of things that are involved in programming the game.
  8. Whether you’re doing the art/sounds or someone else is.
  9. How long it takes them to do make the art and sounds, or how long it takes you to.
  10. How many Unity bugs get in your way.
  11. How many real life events get in your way.
  12. How motivated/determined you are.
  13. How well you can maintain that motivation/determination.
  14. How healthy you are (this one isn’t mentioned very often but it’s rather important).

On and on…
