I have many years experience with business app development but always wanted to play around with creating a game. I recently have gotten interested in mobile game development. I guess my question is that is Unity the best tool for creating a mobile game such as Game of War or Mobile Strike? Where would I even get started looking for resources on learning things like tile mappings etc? Any help and pointers would be appreciated?
Unity is capable of creating just about anything you can think of. It really comes down to taking the time to learn how the editor and scripting api work, and learning what Unity provides you to work with out of the box.
Tile mapping is a new feature in the current Unity Beta, which is available for download but is not reliable enough for production as things are subject to changing and breaking.
Take a look at the tutorials Unity provides:
