Hey Derpost,
You can build a browser-based game using the following:
- You’ll need a nice design
- HTML, CSS & JavaScript for the UI
- PHP to handle logic
- MySQL to store data
If you don’t have sufficient knowledge in any of the above and you’re planning on building it yourself, it’s going to be a while before it’s possible as you’ll have a lot to learn. On the bright side, if you’re learning this to build something you’re really interested in you’ll enjoy it, don’t get me wrong… you’ll still be pulling your hair out now and then just like the rest of us , but you’ll be motivated to keep going.
Best of luck and keep coming back here anytime you need help
