Don't move to Arch. It's a great distro don't get me wrong but it's not for someone who isn't quite familiar with Linux. You need to choose every package on your system and configure it all.... Give yourself some time to know Linux.

Ubuntu is a great distro with a great out of box experience. The company behind it though has been making some choices I don't much care for so I've moved away from them. (They created a pretty crappy new packaging system, then started making the old, reliable packaging system use the new one without user consent)

OpenSuSe Tumbleweed is a great option. It has sane defaults, and nice versions of KDE and GNOME (two popular types of desktop environments, I'd recommend KDE if you're new to Linux - it's closer to the desktop philosophy you're used to. GNOME is great too but it's very opinionated and non-traditional, not for everyone.) It's also a "rolling release" distro, which means there's no big releases it just gets updated over time and provides you with very up to date packages. It's known to be quite stable which is unusual for a rolling-release distro (like Arch, for example).

Fedora is also a great choice - just follow a guide on how to get some media codecs on it (Fedora is big on not including software that isn't 100% open, but it's easy to add the few things you'll need). But it provides a great package manager, great KDE and GNOME versions, and all around very sane and stable. This is a traditional release distro with new versions every 6 months. You'll still get security and minor software updates between releases.

Whatever you choose, I think you'd be very surprised at what you CAN play under Linux with no problem. Outside of a few games (mostly due to anti-cheat which unfortunately rules out some - but not all - of the more popular multiplayer competitive games) there's really not much that doesn't run on Linux already nowadays.
