Questions about how to fix a bug and some game design questions

Hello! I just downloaded the launcher, and I’m looking to try my hand at creating games after one of my friends suggesting it. However, I’m having a few problems and a few questions about a certain game type.

First off, I booted up the Unreal engine Launcher, and I can’t get it to work. It keeps on going to verifying, shutting down, and then going back to verified again. I can’t get it to work at all and I’d love to try it out. Is there any way to fix it on Mac?

Second off, I’ve had an idea for a 2D fighter for a while and I’m wondering if this is a good program to make a fighting game and if there is any tools to help me through it. Thanks if you can!

Have you checked out these posts on the answerhub?

If that game is for PC, then yes unreal is fine for 2d fighting game. However doing that for mobiles as first project in unreal may be hard. For mobiles unreal is overkill atm, give it 2-3 more years for mobile hardware (and download quotas) to catch up.

Make sure you have installed all required components like visual c redistributable, direct x, etc. List of packages should be somewhere on answerhub. Sometimes fixing broken package install will help with unreal.
