but you can forgot to use ultra hd textures and a big map if it possible xD
in fast: yes you can create games if you have the know how but you cant make Crysis 4 ;)
(if i have understand anything wrong say it pls)
Games like the online shooter games are among the easiest to create and you are by no means limited to OpenGL.
You can make games of good quality and reasonable complexity using DroidScript.
Search in this group for "spaceshooter" or "three.js"
But to build a polished game in any environment you will need to put in quite a lot of effort.
The best way to approach this has to be to become familiar with DroidScript first.
Start by examining the samples that come with DroidScript and build your own simple projects to begin with and get more complex as you learn more.
We can help you with your journey of discovery if you post problems you find along the way and later, when you have the skills, we can help you with problems you find while developing your game.
But we cannot help you with both at the same time. A grasp of the basics is essential to understand what is needed for a complex game.
That, combined with its ability to offer complex interaction with the device makes it ideal for a beginner to become an expert in a relatively short time without having to move to other environments.
