I recommend trying another linux distro for a while. Arch has a pretty steep learning curve. So big respect for getting it to work as a first distro, but there is a lot of stuff you have to setup manually that just works on other distros. If you got more stuff working and get a little more familiar you can always go back to arch.

I use arch nowadays, but the first time i tried to install it i basically gave up a few times. If you just want to try it out in order to learn then it's perfectly cool to take some time. But if your goal is to play games then arch is just a means to an end. Then it becomes really annoying, because you cannot reach your goal.

Just a heads up, but gaming on an external drive with bazzite is a nightmare (if you end up trying to go that route).
